Manchester City boss Roberto Mancini remains angry by Vincent Kompany's dismissal in their FA Cup defeat to Manchester United.

He remains convinced his captain did nothing to warrant dismissal when he made his fateful tackle on Nani 12 minutes into the FA Cup derby.

"In 30 years I have never seen a sending off for a tackle like this," he said.

"For me there was no danger. If there was danger, Nani was there, he was the player near the ball. He would have said something about it. He didn't say anything.

"Last week I watched three or four players in the Premier League who made a tackle worse than Vinny, with the same referee. He did nothing. No yellow card. Nothing."
