Manchester United knocked holders Manchester City out of the FA Cup with a 3-2 third round win in an incident-packed derby at Eastlands on Sunday.
Wayne Rooney scored twice, netting either side of the controversial sending off of City captain Vincent Kompany, with Danny Welbeck also on target to make it 3-0 before the break for the visitors
But City pulled a goal back early in the second half when Aleksandar Kolarov bent a free-kick round the wall from the edge of the box.
And 10-man City struck again when Sergio Aguero made it 3-2 in the 65th minute following a mistake by United substitute Paul Scholes, summoned out of retirement by manager Sir Alex Ferguson following an injury crisis.
Premier League leaders City, three points in front of champions United at the top of the table, pressed for an equaliser, with Kolarov going close from a second free-kick in stoppage time, but Ferguson's men held on.
