20 Biggest Deals We Might See on Transfer Deadline Day

After months of trawling through the papers, skimming through various articles online and even receiving the odd text detailing your club's move for a highly-rated player, the transfer window has reached its final day.

Of the window so far, Tottenham have arguably taken the lead in the transfer market, securing world-class players such as Roberto Soldado and Erik Lamela from Valencia and Roma respectively.

Additionally, their London rivals Chelsea have been shrewd also, snapping up Anzhi Makhachkala's star duo Willian and Samuel Eto'o for a combined £32 million.

But while the futures of Wayne Rooney and Luis Suarez have ultimately been decided, questions remain over the future of Gareth Bale, whose protracted move to Real Madrid has been further delayed and could be forced through at the 11th hour.

Away from the Premier League, there have been some mammoth transfers to go through, especially in Ligue 1 where Radamel Falcao signed for Monaco in a £50 million deal, and Edinson Cavani joined French champions PSG from Serie A runners up Napoli.

Join us to find out which deals could go through on Deadline Day, as we've picked 20 of the biggest we think might happen.

Ander Herrera (Athletic Bilbao to Manchester United)

After pursing a marquee signing for the whole of the summer, David Moyes may finally sign a big-name playmaker after admitting defeat with several other targets.

Cesc Fabregas, Mesut Ozil and Luka Modric have all been on the Manchester United manager's shopping list, per ESPN, but the trio have opted to stay put at their respective clubs.

But after being alerted to Athletic Bilbao playmaker Ander Herrera's €36 million buy-out clause in his contract, the Red Devils could swoop for the 24-year-old playmaker, according to Spanish radio station Cadena Cope. 

The current offer stands at €30 million but, with the Basque club in no hurry to sell, Moyes may need to increase his offer if he is to get his man, and this one could go right to the wire as the champions look to strengthen their squad.

Leighton Baines & Marouane Fellaini (Everton to Manchester United)

Even though Roberto Martinez claims Leighton Baines has not asked to leave Everton, per Goal.com, the Spaniard must be concerned at Manchester United's relentless pursuit to sign him.

The England left-back has been targeted by his former manager David Moyes, who took over at Old Trafford this summer, and has so far had two bids rejected for him and his teammate Marouane Fellaini, according to The Telegraph.  

Moyes was said to have offered £36 million for the pair, but at this late stage in the window, it could cost the Premier League champions up to £50 million for the dynamic duo. 

With the list of targets decreasing by the day, it could take a last-minute dash up the M62 for Manchester United to sign both players, or perhaps only one. 

Toby Alderweireld (Ajax to Atletico Madrid)

Ajax are bracing themselves to lose several of their talented stars, and Toby Alderweireld could be another who departs the Amsterdam Arena.

Despite being targeted by Liverpool and Norwich originally, it now appears that the highly-rated Belgium international will snub a move to the Premier League and join La Liga outfit Atletico Madrid, per the Daily Mail.

The 24-year-old has clocked up over 185 appearances during his five years at the club and has already turned down a move to Spartak Moscow this summer.

However, it now seems to be that he will be linking up with Diego Simeone's side for their forthcoming campaign and is expected to sign a long-term deal which will see the Dutch club pocket around £8 million. 

Eliaquim Mangala (Porto to Chelsea)

Porto are set for another transfer tug-of-war this summer after their French defender Eliaquim Mangala was linked with a move to the Premier League.

Chelsea and Manchester City are said to be keen on bringing the France international to England, with The Mirror suggesting that Manuel Pellegrini could pay his buy-out clause, currently set at a whopping £40 million.

The 22-year-old has excelled for the Portuguese club since signing from Standard Liege two years ago, and was an instrumental part of their incredible unbeaten season in the 2012-13 campaign.

Jose Mourinho is known to be actively looking for defensive cover and could be set to make a move with chief executive Ron Gourlay refusing to rule out further additions before the window closes, per Sky Sports.

It has the potential to be one of the biggest deals of the transfer window if an offer is made, so we advise you watch this space.

John Obi Mikel (Chelsea to Galatasaray)

Galatasaray are thought to be back in the running for John Obi Mikel as Chelsea look to reduce their overflowing squad before the end of the deadline. 

The 26-year-old, who joined Chelsea from Lynn Oslo in 2006, has recently seen himself fall down the pecking order with the arrival of Marco van Ginkel and the return of Michael Essien from his loan spell at Real Madrid.

Jose Mourinho is yet to deny that Mikel could leave, and with the Turkish giants willing to offer £10 million according to The Express, the Nigerian could be on his way out of Stamford Bridge.

One stumbling block to any deal is that the holding midfielder has travelled with the squad to the European Super Cup clash against Bayern Munich, but a deal could still be agreed on deadline day.

Burak Yilmaz (Galatasaray to Lazio)

It could be a case of one player in, one player out for Turkish champions Galatasaray as their star striker Burak Yilmaz looks set to complete a dream move to the Serie A.

Despite past interest from Real Madrid and Chelsea, the 28-year-old has been targeted by Coppa Italia winners Lazio, who want a long-term replacement for veteran striker Miroslav Klose.

According to Yahoo Sport, the Roman club want to pay €9.5 million plus add-ons, but at present the two clubs' valuation are too far apart, with Galatasaray holding out for €18 million.

Yilmaz, who played for Fenerbahce and Besiktas before leaving Trabzonspor for Gala in a €5 million deal last year, was in magnificent form last season, scoring 32 goals in 37 games, including goals in the Champions League.

Lazio fans will be praying the club reach an agreement soon, with the Turkish outfit's sporting director currently in Rome negotiating the transfer. 

Angel Di Maria (Real Madrid to Arsenal)

With the impending arrival of Gareth Bale, there are several players at Real Madrid whose future currently is currently up in the air.

And none more so than Los Merengues winger Angel Di Maria, who could be sacrificed by Carlo Ancelotti to make way for the Welsh wing wizard.

Arsenal are said to be interested in signing the tricky Argentinian wide-man, who joined the La Liga runners-up three years ago from Benfica in a £25 million deal.

The Guners have reportedly made an offer worth £25.6 million, per Goal.com, which will see Real Madrid receive what they paid for the 25-year-old, although it's not yet clear whether the former Racing midfielder would want to leave the Santiago Bernabeu.

Di Maria would certainly tick the boxes that Arsene Wenger requires to strengthen his squad and no doubt, the supporters will be praying they can close a deal.

Fabio Coentrao (Real Madrid to Spurs)

It's surprising that not one team has made a concrete offer for Fabio Coentrao this summer, although that could well change by deadline day.

According to the Evening Standard, Tottenham manager Andre Villas-Boas is interested in bringing his compatriot to White Hart lane after Coentrao admitted he wants to leave Real Madrid.

The 25-year-old left-back, who is a current Portugal international, has failed to secure regular football since moving from Benfica two years ago, and recently revealed he has asked to leave in a bid to play at the World Cup next year with his country,

A loan move would be ideal, but with Ancelotti lining up a replacement (see next slide) it is thought that a bid of around £15 million is required to secure his signature.

Guilherme Siqueira (Granada to Real Madrid)

A somewhat surprise move from Real Madrid sees a deal lined up for Granada's brilliant full-back Guilherme Siqueira.

The 24-year-old was previously linked to Everton and Liverpool after an impressive season for the ambitious La Liga outfit, but it appears that Real Madrid's financial muscle has seen them pull ahead in the race to sign him. 

ESPN report that the deal was struck between the two club's executives on Monday when Carlo Ancelotti's side won 1-0.

However, the move hinges on whether the club can offload Fabio Coentrao before the transfer window closes, with the Brazilian poised to put pen to paper on a deal to sign for the Spanish giants as soon as the Coentrao's exit is confirmed.

Martin Demichelis (Atletico Madrid to Manchester City)

In one of the more bizarre transfers of the summer, Martin Demichelis could have his third club in as many months.

Atletico Madrid signed the veteran defender on a free transfer after his deal at Malaga expired, but just a month after arriving, the Argentine centre-half could be departing for pastures new.

Manchester City boss Manuel Pellegrini, who brought Demichelis to Malaga back in 2011, is reportedly willing to pay £5 million for the ex-Bayern Munich man to take him to the Etihad Stadium, per The Guardian.

Pellegrini is short for cover after captain Vincent Kompany was ruled out for a month with a hamstring injury, and the signing of Demichelis could really bolster their options in defence.

Kaka (Real Madrid to AC Milan)

In one of the shocks of the transfer window, Real Madrid star Kaka has told the club he wants to leave four years after signing in a world-record deal.

The 31-year-old, who scored twice in a 4-0 friendly win over Deportivo La Coruna, told the Spanish press after the game that he wants to leave before the close of the transfer window, per Goal.com.

It's easier said than done, with Kaka's wages only affordable for the likes of PSG, Manchester City and Chelsea. A move to the MLS has been mooted in the past, with ESPN previously suggesting New York Red Bulls could be in the market.

Having said that, with Premier League sides such as Arsenal and Manchester United looking for a marquee signing, the Brazilian could fit the bill. 

Yohan Cabaye (Newcastle to Arsenal)

Arsenal will have to come up with a "world class offer for a world class player", Alan Pardew said after Newcastle rejected an initial bid of £10 million for Yohan Cabaye, per The Telegraph.

The Frenchman only joined the Magpies from Lille two years ago for £4.5 million and during his time at St James' Park, he has excelled to the extent whereby he has outgrown the club.

As a result, Cabaye is refusing to play in a bid to force through a move to Arsenal, but it looks as if he may have to stay for the time being.

The 26-year-old has been admired by Arsene Wenger for a long time and it seems that a £15 million move would enough to force Newcastle's hand, with other transfers waiting to go through for the North East club, but whether Wenger will stump up the cash or not remains to be seen.

Demba Ba (Chelsea to Newcastle)

After Chelsea secured the signing of Samuel Eto'o, the inevitable doubts surrounding Demba Ba's future intensified with Newcastle rumoured to be interested in re-signing their former striker, per Sky Sports.

Ba only joined the Blues in January for a fee of £7 million but has struggled to make an impact, scoring just six goals in his eight months at the club, and has been heavily tipped to leave the West Londoners.

He has fallen down the pecking order at Stamford Bridge, with Jose Mourinho preferring Fernando Torres and Romelu Lukaku in the campaign so far.

A deadline-day, loan move looks to be on the cards for the Senegal striker as he looks to find regular first-team football. 

Mamadou Sakho (PSG to Liverpool)

PSG's summer spending seems to have come at a price, with speculation suggesting that youth product Mamadou Sakho could leave the French champions after 11 years with the club.

Liverpool and AC Milan are said to be monitoring the 23-year-old's situation at Parc des Princes, with the France international keen to play regular football.

Sakho made just 34 appearances last season behind Alex and Thiago Silva, and the situation is unlikely to improve under Laurent Blanc, who signed young Brazilian defender Marquinhos for £35 million this summer.

The Reds are more willing to seal a deal now that Kolo Toure is ruled out with a groin injury and could go as high as £13 million for the highly-rated centre-half, whose contract expires next summer, per The Mirror.

Shinji Kagawa (Manchester United to Atletico Madrid)

Manchester United fans have been desperate for the club to sign a world-class name, but one of their talented playmakers could soon be on the move just a year after joining.

Shinji Kagawa, who joined the Red Devils in a £13 million deal a year ago, has failed to impose himself on English football thus far and has struggled with injuries, making just 26 appearances in thew 2012-13 campaign.

Atletico Madrid and former club Borussia Dortmund are said to be eyeing a move for the 24-year-old Japanese star, although David Moyes is keen for the ex-Cerezo Osaka man to stay put, per The Daily Mail.

It seems unlikely at this stage, but with Kagawa not featuring at all in the game against Chelsea, a bid of around £20 million could make things interesting on the final day of the window. 

Florian Thauvin (Lille to Marseille)

In another remarkable story, France Under-20 star Florian Thauvin finds himself in a spot of bother after signing for Lille this summer.

The 20-year-old sealed a move to the French club before the Under-20 World Cup in Turkey, but after the tournament, set his sights on a move to Marseille and refused to train until the move went through.

Lille are adamant that their star asset won't be sold to a Ligue 1 rival, as Thauvin is yet to play for the club after going out on loan to Bastia.

But with interest from Liverpool and Arsenal cooling, per The Express, it could be only a matter of time before Thauvin is making the move to the Stade de Velodrome. 

Andriy Yarmolenko (Dynamo Kiev to Liverpool)

A target long on the radar of Liverpool, Ukrainian star Andriy Yarmolenko could finally make his long-awaited move to the Premier League on deadline day.

With his die Dynamo Kiev signing Younes Belhanda and Jeremain Lens earlier this summer, Yarmolenko could be sold to raise funds after being priced out of a move in the past.

The 23-year-old is predominantly a left winger but also can play as a forward and has scored 11 goals in 32 caps for Ukraine.

Reports in Italy, via the Daily Star, suggest a £19.8 million move could be brokered in the days leading up to the transfer window as Brendan Rodgers seeks to replace Stewart Downing, who left for West Ham earlier this month. 

Joshua Guilavogui (St Etienne to Arsenal)

Arsenal are reportedly keen on on bringing in France's next sensation Joshua Guilavogui from Ligue 1 side St Etienne as Arsene Wenger looks to spend some of the money available to him.

The 20-year-old, who is already a France international, has shown time and time again why Europe's top clubs have scouted him thoroughly with some consistent mature showings in midfield. 

However, The Daily Mail suggest that The Gunners are in pole position to lure the wonderkid from his roots to join the Premier League side, should a move for Cabaye fail.

This could be one the last transfers to go through if Newcastle opt to keep their star midfielder, with Guilavogui, hailed as the next Patrick Vieira, likely to cost around £8 million.

Christian Atsu (Porto to Chelsea)

Ever since letting Salomon Kalou join Lille last summer, Chelsea have been looking for a cheap alternative without much success.

But now, after stealing ahead of Liverpool and Tottenham once again, the Blues look set to sign Porto's Ghanaian winger Christian Atsu in a cut-price £3.5 million deal, according to The Telegraph.

Atsu is a fast, agile winger who has been something of a sensation at the Estadio do Dragao in his two years at the club, and was tipped to have a big part to play due to James Rodriguez's departure to Monaco.

It's likely that the 21-year-old will play a bit-part role at the club or move out on loan, so you can expect Chelsea to complete the deal before the deadline, providing he is clear for a work permit.

Gareth Bale (Spurs to Real Madrid)

And finally, the one you've all been waiting for. Okay, you haven't.

Gareth Bale's world-record £86 million transfer to Real Madrid has edged closer and closer only to hit hitches and suffer delays, and it's getting to the point now that fans are starting to get frustrated about the lack of progress.

Tottenham have already signed Bale's replacement, with Erik Lamela joining from Italian side Roma in a £30 million transfer, and so the North London club are eager to get the transfer sorted as soon as possible.

In the meantime, the 24-year-old has been absent from training and could be fined by Andre Villas-Boas for his conduct, per Sky Sports. While his dream move appears to be more inevitable with each day, this could be signed and sealed within minutes of the deadline.

I think we speak for everyone when we say, "Sign on the dotted line, Gareth!"
