What is wrong with Drogba?
A couple of weeks ago he made some very unprofessional statements saying that he wanted to leave Chelsea, that the club was broken and that something was wrong, and now i read that he said that he "felt disgusted when he joined Chelsea".
Even though Drogba was a diver i had respect for him, I thought/think he is a good footballer who has played some amazing games, but I've lost respect for him.
