Jose Mourinho says that he is prepared to take a gamble on Diego Costa for Chelsea's Premier League clash with Manchester United on Sunday - provided that the striker can come through a training session unscathed.
Costa has missed the Blues' last two matches against Crystal Palace and Maribor after returning from Spain duty with a groin problem and then contracting a virus which saw him hospitalized.
But Mourinho revealed on Friday that Costa still had a "little chance" of making an appearance at Old Trafford and the Portuguese insists that he would not hesitate to include the Premier League's joint-top scorer in his squad if he proves himself fit enough.
"I don't protect before a Man United game unless he cannot play," Mourinho told reporters, "but, if there is a chance of play, Old Trafford is not a place to protect players. If he is ready to play, then he plays.
"He has to show [on Saturday] in the training session that he is capable. He has to train without any limitations - to make a complete training session with the other guys without any kind of protection."
Chelsea are already without striker Loic Remy, who is expected to be sidelined for at least two weeks with a groin problem sustained against Maribor, while Didier Drogba is still short of full fitness. Andre Schurrle, however, should return.
