A lot of big players could be on the move this summer, and fans of the game can look forward to some interesting rumours over the next few weeks.
Little shifts in power across Europe may force some of the top clubs act, and their may be a lot of activity.
Here are some of the most interesting transfer rumours to look forward to, this summer.
Another Brazilian defender, Thiago Silva, has been linked with Barcelona a lot more, but it seems that David Luiz will get his share of interest as well.
The Mirror reports that Luiz is at the top of Barcelona's list.
"Outgoing Barcelona boss Pep Guardiola is a big fan and his already-appointed successor, current assistant Tito Vilanova, is also keen, although it would take a bid in the region of £30m to prise him out of the west London club."
Barcelona really needs defensive cover, and Luiz could be a good match for the club. He has only been at Chelsea since January of 2011, and he may not be ready to move just yet.
There are much cheaper options like Albert Botia available, so it will be interesting to see which route Barcelona takes.
Seydou Keita's experiences with Barcelona make him a very valuable catch for teams in need of his expertise.
According to Talksport.com, both Liverpool and AC Milan are interested in signing the player this summer.
Milan is used to having veteran players in the side but it is confusing as to where Liverpool could see Keita fitting into their squad, despite his experience and talent.
Losing Keita wouldn't be a huge deal for Barcelona, but one would think they still need a player like him to re-assert their dominance next season.
Ezequiel Lavezzi is rumoured to be on the move this summer. An article from the Daily Mail cites a dispute between the Argentinean attacker and Napoli president Aurelio De Laurentis.
Lavezzi has a reported £26 million buy-out clause, and that is a figure both clubs can match with ease. His departure would hurt Napoli's continued growth and may have an effect on whether the team's two other attacking stars, Edinson Cavani and Marek Hamsik, decide to move on.
Lots of fans are interested on when or if these three players would leave the club, and it looks like Lavezzi may be able to give folks an answer soon.
Robin Van Persie has been linked to a lot of top European clubs in the past few months, including Manchester City, Real Madrid and Barcelona. Juventus is the latest team to join that list.
Signing Lukas Podolski may have helped Arsenal entice Van Persie into staying, but he could end up being just a replacement.
The Dutchman will be meeting to talk with his employers about his contract and his future at the club, and Arsenal fans will hope that everything goes well where that is concerned.
Barcelona needs some help at the back, but they have been linked with Athletic Bilbao forward Fernando Llorente.
Llorente would provide the Blaugrana with a forward option that they certainly don't have at the moment. While Llorente is quite the opposite of the forwards Barcelona normally get, but he does have qualities that will help him fit into the club.
Bilbao has a solid team with some great talent but Barcelona could tempt him the possibility of Champions League play and the ability to challenge for La Liga titles every year.
Considering their offensive woes in the Premier League this year, Liverpool needs some more talent up front. That help could come in the form of Frenchman Olivier Giroud.
Kenny Dalglish reportedly went to watch the player this season and the interest could become real.
Giroud has been in great form this season for Montpellier, and is a major factor in their current standing in the league.
According to the Metro, Liverpool will be in the hunt for Dutch talent Luuk De Jong. All these forwards being linked to Liverpool makes one wonder about the future of a certain Andy Carroll.
Liverpool would do well to get a player like De Jong, though it is uncertain that he could keep up his great scoring form in the higher level of the EPL.
The future of Neymar has attracted a lot of attention but he's not the only young Brazilian star around.
The Metro reports that Lucas Moura has attracted the interest of Manchester United, and his current club Sao Paulo, has set a £ 40 million price tag for the player.
Signing a player with Moura's undoubted talent and potential is nothing new to Manchester United. but the youngster may not be the player to immediately push them further next season if he is bought.
Robert Lewandowski emerged as an important player for Borussia Dortmund this year, with his 20 league goals helping the team retain its Bundesliga title.
Top English clubs Arsenal, Manchester City and Chelsea have been linked to the Polish striker thanks to his refusal to enter negotiations about a contract extension until after Euro 2012.
Arsenal may be out of the running already, thanks to their capture of Lukas Podolski, but the other two clubs could see Lewandowski as a good option for their team.
Chelsea may be the better club for the player, considering the age of Didier Drogba and the lack of form of Fernando Torres, but the fact that they may not be in the Champions League next year could work against them.
With Mario Balotelli likely to leave, Lewandowski could make it into the clubs ranks but would face extremely tough competition from the likes of Sergio Aguero and Edin Dzeko.
Dortmund won't let the player go easily, and considering the fact that Dortmund will be in the Champions League like both Arsenal and Manchester City, he may decide to stay. Anything can happen though.
Paris Saint-Germain went on a huge shopping spree last summer and it looks like they are set to repeat the act this summer.
PSG has been linked to South American stars Luis Suarez, Kaka and Gonzalo Higauin. The French Club has shown it has the money to pay for players of such quality, but they would still be hard targets to get.
Liverpool is unlikely to let Suarez go despite his disciplinary problems, Kaka has seen a resurgence in form this season and was product enough to help his team recapture the La Liga title this year.
Higuain is probably the easiest option, considering what you'll see in the next slide.
Karim Benzema's form this season has knocked Gonzalo Higuain down the depth chart a little. Higuain has begun to question his future at the club and has said he would be interested in a move to Italy.
Chelsea and Juventus seem to be the first options right now, but as his situation becomes clearer, Higuain will have no shortage of suitors. Both clubs could use a prolific striker like the Argentinean, but if it becomes a bidding war, Chelsea could have the upper-hand.
Manchester City already has the best attack and defense in the league in terms of goals scored and goals conceded, but current boss Roberto Mancini is looking to add some depth in the back-line.
The Metro reports that Andrea Ranocchia is a target for the club. Ranocchia would join youngster Stefan Savic as a possible future starter and a replacement for the likes of Vincent Kompany and Joleon Lescott.
According to Goal.com, Real Madrid has shown some interest in Anderlecht star Lucas Biglia.
"The Santiago Bernabeu side are in the market for reinforcements in the centre of the pitch as Lassana Diarra is expected to depart the club, and they supposedly see the 26-year-old as the perfect replacement."
Biglia has been linked to teams like Arsenal in the past, but the English club never showed any real interest. Biglia should be wary of joining a club like Real Madrid, as he would possibly be coming in to replace a player who has been a rotational player for the team during a good amount of his time there.
Sir Alex Ferguson may be on the lookout for a playmaker this summer, and Goal.com reports that Shinji Kagawa is one of the players on his list.
Things look good for United if they make their interest real, as Kagawa recently rejected a contract offer from Borussia Dortmund.
The Japanese midfielder would be a cheaper option than the likes of Wesley Sneijder or Luka Modric, and could end up having a similar impact on the field.
According to Talksport.com, Real Madrid is looking to Benfica's Axel Witsel for midfield reinforcement.
Witsel, a reported long-term target of Manchester United, has only been at Benfica for one year but could be tempted by a bid from two of the world's top clubs.
Everton loses its top players year after year, and Marouane Fellaini may join that list this summer. Chelsea has been linked with the Belgian player, in what is sure to be the first of many rumours involving the club.
With a continually aging squad in his hands, Roman Abramovich is interested in revamping his team in order to mount a significant challenge.
Fellaini could be the start of that overhaul.
Damiao has been linked to clubs like Tottenham before this, but a move to Italy could be a good fit for the player.
Juventus is on the verge of winning the Serie A and could use a player like Damiao to possibly retain the title and provide some firepower in the Champions League.
Wesley Sneijder has been linked with an interesting move to Spartak Moscow. Sneijder has been out of form this season, and has been linked with Manchester United since last summer.
United may be moving on to other targets, but Sneijder isn't short of suitors. With Spartak's interest and the previous rumours concerning Anzi Makhachkala, the Dutch playmaker could see himself moving to Russia in what would be one of the most surprising moves of the summer.
Arsenal, Liverpool, AC Milan and Juventus have all been linked with Udinese's Pablo Armero. Armero would be a valuable asset for all these clubs. Especially AC Milan who are in need of a left-sided defender.
His starting price could be around £8m, but if all these clubs try to go after him at once, that fee could rise.
Hulk's release clause—coming in at around £80 million—has stopped a lot of suitors so far, but the French club seems to be set on capturing their man.
If Hulk does move this summer, it could end up being the most expensive signing during the transfer window.
