"For me Rooney is a very good player," Capello told Sky Sports News.
"He's young. Sometimes his reaction is not so good, but he's a good player and a good man.
"I think at that moment he was a little angry because they were losing and he was red-carded. That's why he did this. But there's no problem with Rooney in the future.
"I spoke with him. I'm very happy after I spoke.
"Sometimes we need to be a little bit aggressive during the game. I hope the level of aggression will be balanced.
"This is very important. I'm sure he'll play very, very well with us.
"We want the team to be aggressive. Good aggression."
