First up is none other than Zlatan Ibrahimovic. The big Swede's contract at PSG is up this summer and he has made it no secret that he won't be sticking around in Paris. Although the serial goalscorer seems to have his heart set on a move to the Premier League, I'm sure some ridiculous wages would tempt him anywhere. Ibrahimovic would undoubtedly be a great signing and could be the difference between a league title and a near miss!
Next is Manchester United's (for now) Michael Carrick. The deep-lying playmaker has been a part of the United set-up for 10 years now and looks to be moving on when his contract runs out at the end of the season. An established Premier League player, Carrick could be a decent signing for a number of clubs on a free.
Another Premier League player out of contract in the summer is Chelsea's John Terry. The defender could still be offered a short extension at Stamford Bridge but this is looking more and more unlikely. Terry isn't getting any younger but no one can doubt his ability.
Mathieu Flamini's name can be added to the list too as his contract his up this summer. The Frenchman could be on his way out of the Emirates and with so much experience behind him, I doubt he will have too much trouble finding a new club.
Martin Demichelis is another who may have to look for a new team this summer as his deal expires in June. The Argentinian has been prone to a few errors during his time at City but has also shown he can be a top-class defender on his day. Demichelis is reaching the end of his career but has another few seasons in him yet and could be a good bit of business.
Who do you think would be the best free transfer?
