With less than two months to go until the January transfer window opens, Premier League clubs are now having to decide whether to keep hold of some of their star players or risk losing them for free next summer.
Didier Drogba, Nicolas Anelka and Jose Bosingwa are among five first-team players at Chelsea whose contracts expire at the end of the season, and manager Andre Villas-Boas could decide to cash in on some of his fringe players in the new year.
Dimitar Berbatov is also out of contract in the summer, though Manchester United hold the right to extend the player's deal by a further year. But with Paris Saint-Germain being linked with a move for the Bulgarian, the Red Devils will need to exercise the clause before he is allowed to discuss a summer switch in January.
Arsenal's Tomas Rosicky and Fulham's Andy Johnson may also be on the move if they cannot agree fresh contracts with their clubs, while time is running out for Blackburn Rovers and Bolton Wanderers to tie top-four targets Junior Hoilett and Gary Cahill down to new deals.
