Diego Costa has reportedly refused to train with Atletico Madrid after the club fined him for his behavior against Barcelona.

Costa is currently serving a 8-game ban after getting sent off in the match.

Diego Simeone stood by his striker.

"Costa is an animal who can do things that make us suffer like what happened at the Nou Camp when he really needed him. But I don't judge players for one incident, I evaluate them for everything and there are many more positive than negative things about Diego," said Simeone.
