Arsenal fans have noticed the reaction of Nacho Monreal when Danny Welbeck won a penalty for the Gunners during their 3-1 win over AC Milan on Thursday in the Europa League.

The striker silenced those who doubted his ability as he went on to net a brace during the game, however controversy surrounded the penalty which he won during the first half after he appeared to dive in order to win a spot-kick which levelled the game 1-1.

Arsenal fans have noticed Monreal's reaction to the penalty which was taken by his team-mate.

As Welbeck runs to take the penalty, the defender has his hands on his head and is looking at the floor, nervous that his team-mate will not find the back of the net.
