Champions United won only three of their first eight Premier League games under new boss David Moyes this season.
But the 1-0 win against Arsenal moves them only five points behind the Gunners in fifth place.
United’s Phil jones, says: “People want us to fail because we have won the league so many times – everyone hates the best clubs,”
Robin van Persie’s goal against his former team at Old Trafford on Sunday extended United’s unbeaten run in all competitions to nine games, and was their third consecutive victory in the league.
But before that recent run, United – led by former Everton boss Moyes, who replaced Sir Alex Ferguson in the summer – had collected only 11 points from their first eight games, their worst start in 24 years.
