Definitely mate. The problem with Diego Costa at that time was that he simply wasn't discilplined enough. Always a hard worker, very raw when he came to Europe because he hadn't played organized football before he turned 16 which is also one of the main reasons why he got sent off so often. I read an interview with him where he said that he's finally realized how to play in an organized enviroment, without the dirty tricks and stupidity he showed at Celta, Albacete, Valladolid (at times, despite the positive stint he had) and during his first year at Atlético when he finally got a shot at playing for the senior team without being loaned out. I think the injury he suffered last summer changed him and brs, he's clearly showed that he's capable of a lot of good things at Rayo. 10 goals and 4 assists last year.zori, do you remember like 3-4 years ago when you insisted Diego Costa wasn't good enough? I was always a fan of him. Good player.
