Chelsea boss Jose Mourinho has declared Diego Costa now fully fit. The striker has "totally recovered" from persistent hamstring and groin problems, and Mourinho is looking forward to the striker firing on all cylinders once again.
"In these past two weeks he had a little bit of a holiday," he said. "But the holiday he spent with a Chelsea physio, so even on that small period of holiday he was working many, many hours per day with our physio.
"He keeps going in the right direction and in this moment we feel that he is free of his old injuries."
However, the Chelsea boss did concede that Costa, who has scored 10 Premier League goals this season, may struggle to adapt to the hectic fixture schedule at the end of December.
"We are going to have a period that is new for him," Mourinho said.
"I always think that the Christmas period for players that do it for the first time in their careers is more difficult."
