Arsene Wenger says he has no problem shutting out the criticism he is facing but has called on Arsenal fans to back the team after a wave of discontent among supporters after Sunday's dispiriting loss to Manchester United.

Social media lit up with complaints as Arsenal fans voiced their displeasure following the 3-2 defeat at Old Trafford against an under-strength United side that meant the Gunners lost vital ground in the Premier League title race.

Much of the criticism has been aimed at Wenger, who drew further ire by downplaying the result and praising his team's "spirit" and "commitment in the game -- precisely the qualities many said were missing.

Arsenal have a chance to make up some of the lost ground to leader Leicester when they play Swansea at home on Wednesday, and Wenger said it's vital the fan base is united in support.
