IS DIEGO COSTA REALLY HURT? OR IS IT DIRTY GAMES AGAIN MR MOURINHO.

It is repoted that the Brazilian born Spanish striker Diego Costa got injured again during the Euro 2016 qualifier. Yes I do agree he Diego Costa suffers from hamstring injuries often, even when he was in Spain with Atletico Madrid. But the big question is as Chelsea play Crystal Palace in the E.P.L, Jose Mourinho wants to keep Diego Costa fit for the champion League matches, he is capable of doing all these things.
