Manchester United extended their Premiership lead to nine points with a win over neighbours Manchester City.
Wayne Rooney turned in Cristiano Ronaldo's cross after five minutes and Louis Saha bundled home a second from a Gabriel Heinze cross on half-time.
City lost injured keeper Nicky Weaver, but Hatem Trabelsi pulled one back with a rising drive after 73 minutes.
Ronaldo's late strike sealed the win, before City's Bernardo Corradi was sent off for diving.
Van der Sar: The Dutchman was busier than he really should have been but he kept Blues out easily 7
Neville: Looked like he was going to make early exit with injury but ran it off, and kept Vassell quiet for the most part 7
Heinze: The South American relished the derby in defence but didn't get forward much 7
Ferdinand: Had been in total command but didn't halt Trabelsi in his tracks for City's goal 7
Vidic: The giant Serb again did a great job and got his head on everything. Totally dominated Corradi 8
Ronaldo: Thatcher tried to rough him up at times but he never flinched and won the one-to-one battle 7
Carrick: One or two passes were almost goal assists but they were few and far between 6
Scholes: The architect of virtually every dangerous move United made though he did have a couple of defensive lapses 9
Giggs: Played more derbies than anybody on the pitch but this was one of his quietest - only a few real Giggsy moments 6
Rooney: The most dangerous attacker on the field. Not everything came off for him but had plenty of efforts 8
Saha: On the spot for United's second but this was one of the Frenchman's least dangerous games for a while 6
O'Shea (sub Saha 66): Came on to shore things up but City scored! 5
