Manchester United scored a handy 2-0 win over West Brom Saturday night, but could not put away Manchester City, who beat Norwich City 4-3 to keep their hopes alive in the Premier League.

In other matches, Spurs beat Sunderland 2-1, Wigan blanked Aston Villa 3-0, Swansea doubled the score on Fulham 2-1, Reading surprised West Ham 1-0 and Southampton drew 3-3 with Stoke.

Arsenal played Newcastle in the late match, early Sunday Thailand time. Chelsea play at Everton and QPR face Liverpool Sunday night.

A ninth-minute own goal from Gareth McAuley set Manchester United on their way, but having failed to extend that advantage when they had the better of play in the first half, they struggled in the second as the Baggies grew in confidence.

But Robin Van Persie, brought on as a second-half substitute, scored his 14th goal of the season in the last minute of the match to settle any nerves.

It was a moment of class on a difficult and rainy afternoon at Old Trafford, and ensured that Sir Alex Ferguson will celebrate his 71st birthday on New Year's Eve with his side seven points clear of crosstown rivals Manchester City in the title race.

In a superb match and five minutes of extra time at Carrow Road, Manchester City withstood a determined Norwich.

City surged ahead when Edin Dzeko twice slotted home in the first four minutes.

Anthony Pilkington's free-kick gave Norwich hope but, despite City's Samir Nasri being red-carded, Sergio Aguero added a third for the visitors.

Norwich's Russell Martin scored twice either side of a Dzeko shot going in off the post and keeper Mark Bunn as City held on for the victory.
