Chelsea striker Diego Costa makes no apology for his competitive edge.
For the first time since his £32m switch from Atletico Madrid to Chelsea in the summer, Costa's performances have started to come into question.
Though Costa admits to having problems with his temper, the forward feels he is being hard done by.
Speaking in a recent interview with BT Sport, he said: "I am paying today for many things I have done in my past. Back in those days I couldn't even take a tough tackle without getting very angry.
"I like to win, I hate to lose. I will always give everything I have and remain who I am."
