Manchester United kept within touching distance of the top of the Barclays Premier League thanks to Danny Welbeck's late goal in a 2-1 win at Arsenal.
United knew they needed a win to keep close to leaders Manchester City and they looked on course for victory when Antonio Valencia nodded home Ryan Giggs' cross.
Arsenal rallied in the second half and pulled one back through Robin van Persie, but their hopes of a point were dashed nine minutes from the end when Welbeck steered Valencia's cross home from close range.
