Sporting Lisbon v Chelsea: Jose Mourinho will take 'risk' on Costa

Chelsea manager Jose Mourinho says he will take a "risk" on Diego Costa by starting him against Sporting Lisbon in their Champions League tie on Tuesday night.

Costa, who has scored eight goals in seven league and cup appearances this season, has a fragile hamstring and was a substitute when Chelsea drew their opening group game with Schalke.

Mourinho went on to stress he doesn't "rest people" and always starts with his "best team".
