Manchester United cemented their place at the top of the Premier League table by thrashing West Bromwich Albion.
Dimitar Berbatov's angled finish put them ahead after 22 minutes, with Albion's Paul Robinson sent off before half-time for fouling Ji-Sung Park.
Carlos Tevez scored seconds before the interval after Scott Carson dropped Ryan Giggs' free-kick, and Nemanja Vidic headed home a third on the hour.
Cristiano Ronaldo then struck twice in eight minutes to seal United's win.
It gave Sir Alex Ferguson's side a three-point lead ahead of Liverpool in the title race, with the added bonus of topping up their goal difference in style at The Hawthorns.
United also made it a record 11 straight clean sheets in the league as the pressure piled up on Liverpool and Chelsea, who are in action on Wednesday.
United were lifted by the return of Rio Ferdinand after a back injury - but he was rarely required as the champions strolled to victory.
The huge task facing Albion was made even tougher five minutes before the interval when Robinson was shown a red card by referee Styles for a meaty challenge on Park.
The game was effectively over as a contest seconds before the interval when Carson dropped Giggs' free-kick at the feet of Tevez six yards out, the Argentine slotting home a simple finish.
United got their third on the hour when Vidic arrived to power a corner from Giggs past Carson.
The fourth came after 65 minutes when Tevez released Giggs, who timed his pass to perfection for Ronaldo to score with a precise right-foot finish.
Ronaldo was on target again eight minutes later when Berbatov, who looked suspiciously offside, played him in to beat Carson through his legs.
It was a comfortable night for United - but not for the club's hoping to take away their Premier League crown.
