England coach Fabio Capello accepted Wayne Rooney's dismissal in their 2-2 draw in Montenegro.

Manchester United striker Rooney was shown a straight red for a petulant kick on Miodrag Dzudovic.

"It surprised me, just in front of me he kicked the opponent," Capello told Sky Sports.

"I think the red card is okay, when he lost the ball he kicked the opponent and for the next game he is suspended.

"He is an important player, but sometimes important players don't play well and can make mistakes. It will be a good lesson for him and also for the team."

Capello dismissed suggestions that the arrest of Rooney's father and uncle this week as part of an investigation into an alleged betting scam in Scotland played a part in the striker's frustration.

"The players are thinking always about what is on the pitch, not what is happening away from here, the private problems," he said.

"He wants to be the best, when sometimes you miss the passes and miss the control, he is not happy. I think he was frustrated."
