With the season ticking to a close and clubs across Europe beginning to realize the fate of their campaigns, attention is beginning to shift away from the pitch and onto the summer transfer window.
The signing period never seems to disappoint in distracting one from the dearth of football played in the summer months. Almost every summer, the transfer window offers up a few juicy deals that build the anticipation for the start of a new season.
Looking ahead to this transfer window, what surprising deals might come to fruition and spice up the window?
Here are 10 shocking deals that would certainly provide a spark.
One season removed from captaining his side to their first Premier League title, Vincent Kompany is being linked with a move away from Manchester City to Barcelona.
The Belgian defender was a rock for City in their title-winning season last year, but was injured for portions of this season and had a disagreement with the club over his participation in a World Cup qualifier.
As Barcelona have shown weaknesses at the back, the club is on the search for new center-backs, with Kompany obviously near the top of the list.
Should their captain leave, where would Manchester City be able to find leadership, let alone someone to fill the gap in defense?
On the surface, the rumors of Iker Casillas going to Arsenal seem ridiculous.
After all, the keeper has only ever played for Real Madrid and has over 650 appearances with the club's first team.
However, Casillas has lost his starting role with Madrid over the season thanks to disputes with manager Jose Mourinho.
With Arsenal in need of a solid keeper, Iker could view the Premier League as a new venture that would present challenges he has yet to face. Plus, a starting role for the Gunners would look mighty appealing next to sitting on the bench should Mourinho stay at Madrid.
Iker Casillas changing leagues is unlikely. Should it happen, though, it would mean that a player who captained his nation to three consecutive major titles would be leaving La Liga and going to the Premier League.
One can't dream up a more interesting twist.
A few weeks ago, Luis Suarez was the last player Liverpool could afford to let go.
Now, there is a distinct possibility the club will ship their star striker off to Bayern Munich.
Suarez has been the key for Liverpool this season, scoring over a third of the club's Premier League goals.
However, after Suarez' latest disciplinary incident, in which Luis was banned 10 matches for biting Chelsea's Branislav Ivanovic during a match, the Reds could very well look to move on from the hassle and ship him off this summer.
A top destination for Suarez would be Bayern Munich.
After all, Suarez' agent is the brother of incoming manager Pep Guardiola.
With Bayern flying high this season, adding Pep's tactics and Luis' goalscoring on top would make their run next season even more must-see.
According to The Telegraph, Manchester City could be forced to sell striker Sergio Aguero to Real Madrid this summer.
Madrid have been interested in Aguero for quite some time but haven't been able to lure the Argentinean away from the Premier League.
However, the situation has become quite complicated this season, as Sergio split up with his wife, who left Manchester with his son to take residence in Madrid.
Hence, on a personal level, this would not be a very surprising move.
Given how well Aguero has played for City over the past few seasons, though, this could be a big blow for United's noisy neighbors.
Could that amazing goal on the final day of the season really become a distant memory as Sergio bids Manchester goodbye?
After just one season at Paris Saint-Germain, Zlatan Ibrahimovic is rumored to be looking to leave the soon-to-be Ligue 1 champions for soon-to-be Serie A champions Juventus (via the Express).
The Swedish striker has not spent more than three seasons at any one club throughout his career, but a decision to leave Paris after a year seems strange.
However, Zlatan has had a few run-ins with his club, including a locker room bust-up in which, according to The Guardian, he told his teammates that his sons (five and six years old, respectively) play better football than them.
Even on the pitch, Ibra hasn't seemed quite happy this season.
Then again, it's hard to tell what is going through Zlatan Ibrahimovic's head.
All one can know is that wherever he goes, it will be an entertaining ride.
The speculation all stems from comments Ronaldo made earlier in the season in which he claimed to be "sad" in the Spanish capital.
However, given that Cristiano is still under contract at Real and the club spent £80 million on his transfer, it's hard to imagine a deal being struck for the superstar's sale even if he wants to leave.
If anyone could pull it off, though, it's United boss Sir Alex Ferguson, who always seems to be able to figure out a way to get what he wants.
With a player of CR7's talent, the transfer would no doubt shake up the landscape of European football.
Would a transfer that saw Gareth Bale move from Tottenham to Real Madrid be all that surprising?
No, especially given the incessant reports linking the winger with Madrid, like this one from the Daily Mail.
However, it would be a statement of not only the state of Spurs as a football club but of the Premier League as a whole.
Having just won the PFA Player of the Year award for the second time, Bale would be just the latest two-time winner to then move on to La Liga.
Is the Premier League beginning to leak their best players away? Or can a club like Tottenham hold onto a top player despite the pressures of a Real Madrid?
Either way, it should be an interesting transfer saga.
According to the Mirror, Barcelona could be preparing a bid to lure Manchester United keeper David de Gea to the Camp Nou as a replacement for Victor Valdes.
After a slow start at Old Trafford, De Gea has settled down nicely at United and firmly established himself as the first-choice keeper.
However, the opportunity to play back in his home country could be a big factor for the Spaniard.
It is highly doubtful that United would be willing to part with their 22-year-old starter, but stranger things have happened.
The state of the keeper position at the top clubs would be considerably altered should De Gea end up leaving Manchester United for Barca.
According to the Mirror, Arsenal could be setting up for the return of Cesc Fabregas from Barcelona.
The sale of Cesc in 2011 was a sentimental one for the Spaniard, as he left the Gunners for his hometown club.
It also started an unfortunate trend at the Emirates that saw them sell off their captain for two consecutive summer transfer windows.
Since then, though, Fabregas has not gotten much playing time at Barca, riding the bench behind an incredibly talented midfield.
With Cesc in search of playing time and Barcelona in search of more money, the time could be ripe for a reunion with Arsenal.
Over the past few weeks, many sources (the Daily Mail, for example) have linked Wayne Rooney with a move to Paris Saint-Germain.
While initial reactions of incredulity caused many to write off the rumors, the reports have persisted.
While it is hard to imagine Rooney leaving Old Trafford, his role with the first squad has lessened slightly this season with the addition of Robin van Persie last summer, as evidenced by his place only on the substitutes' bench in the second leg of United's Champions League Round of 16 tie with Real Madrid.
Should Rooney be dissatisfied with these new developments, PSG would definitely be a good option for him as they would offer a more consistent role and boatloads of money.
If Wayne were to decide to depart for Paris, the move would not only be shocking in and of itself, but it might also inspire Manchester United to sign Radamel Falcao or Robert Lewandowski.
