Arsenal fans have taken to Twitter to rage at Shkodran Mustafi after the defender's shambolic defending led to Jesse Lingard scoring Manchester United's second goal.

The visitors had already taken the lead in the first half when Antonio Valencia drilled the ball through Petr Cech's legs.

But Jose Mourinho's men doubled their tally seven minutes later after Mustafi was tacked in his own half.

Anthony Martial was played through and cleverly turned with the ball to set up Lingard.

The Englishman proceeded to score his second goal in a matter of days after finding the back of the net against Watford on Tuesday.

Following the goal, Mustafi went down injured.

Arsene Wenger then substituted the hobbling German for Alex Iwobi in a bid to get his side back in the game.

Arsenal fans immediately took to Twitter to slam the defender.
