The Portugal defender has played a big role in the Blues' success over the past few seasons in a formidable central defensive partnership with captain John Terry.

But Carvalho has been tipped to join former boss Jose Mourinho - whom he followed from Porto to Stamford Bridge in 2004 - when he takes up another managerial post.

Doubts persist about the future of coach Avram Grant while striker Didier Drogba's future is also the subject of speculation and England midfielder Frank Lampard has yet to sign a new contract.

Chelsea missed out on the Premier League title to Manchester United but have a chance to take their revenge in Wednesday's Champions League final.

Carvalho, 29, said: "You have to be prepared because when it's like that, someone goes, someone stays someone comes. I don't know yet if I will stay but I have a contract.

"Everyone has known each other here for a long time and we enjoy each other's company so we have to try to win this last game. It's important.

"We didn't win the Premier League so we have to get a Champions League medal."
