Red-carded England striker Wayne Rooney apologised to his team-mates after making what Fabio Capello described as a "big mistake" in Friday night's 2-2 draw with Montenegro.
Ten-man England hung on in Podgorica to secure a place at Euro 2012, but Rooney will miss at least the first match of the tournament after being sent off - for the second time in his international career.
The Manchester United forward needlessly kicked out at Miodrag Dzudovic with England winning 2-1 and gave German referee Wolfgang Stark little option but to brandish the red card. Rooney joins David Beckham as the only men to have been sent off twice for England.
"He made a silly mistake and said: 'Yes, sorry','' said Capello. "It's a red card. You can't defend that.
"He's a really important player with a lot of experience, and he's played really important games. But he has made a silly mistake. I have seen players like him do that. You can't understand why.''
Coming just a day after his father was arrested as part of a police investigation into an illegal betting scam in Scotland, it raised the question as to whether he should have been picked. Montenegro coach Branko Brnovic was of the view he would have been better left in the stand.
"I read in the newspapers that Rooney has some family problems in England,'' said Brnovic. "To be honest, I didn't expect him to play because those things are serious and it's not easy to concentrate on the game. They're serious, and maybe that's why he did what he did.''
Capello though defended his decision: "I can't enter into the head of Wayne Rooney when he plays,'' said Capello. "I can speak before. I can substitute him. I can find different solutions. But you cannot understand during the game, why things happen. And I don't mean just Rooney.'
"It was not a mistake. He kicked the opponent. Now he will not be able to play the first game in the Euros as he will be suspended.
"He was not happy because he missed some control and some passes. For this reason, I think he reacted. His reaction was to kick the opponent.''
