Micah Richards admits revenge is a motivation for Manchester City as they prepare to face derby rivals United in the FA Cup semi-final.
Richards' second-half header against Reading on Sunday saw City through to a last-four showdown with United at Wembley next month.
City were beaten in the Carling Cup semi-finals by United last season and were also denied a point in last month's Premier League meeting at Old Trafford courtesy of Wayne Rooney's stunning overhead kick.
Full-back Richards acknowledged City did not play well against Reading, but is already looking forward to tackling United at Wembley.
"We're looking to gain revenge for Wayne Rooney's overhead kick," said Richards.
"It's going to be a great game and we'll all be looking forward to it.
"We didn't play well and we struggled to break them down.
"But we showed great resilience to get through and that's all that matters."
The build-up to Sunday's quarter-final had been marred by reports of a bust-up between Richards and manager Roberto Mancini following the Europa League defeat away to Dynamo Kiev.
Richards revealed tempers flared after the match in the Ukraine, but was pleased to see City bounce back by knocking out Reading.
He added: "Certain things were said after the game and tempers were raised.
"But we had just lost 2-0, so nobody was going to be happy. The main thing was we put it right today."
