Arsenal fans were delighted with Unai Emery's substitutes for victory over Manchester United on Sunday.

For Pierre-Emerick Aubameyang's successful penalty, Arsenal's substitutes offered a helping hand.

Matteo Guendouzi and Alex Iwobi were amongst those warming up on the touchline when Aubameyang was taking the penalty after Alexandre Lacazette was fouled by Fred in the area.

But they took drastic action and lay on the ground as he stepped up to ensure supporters behind them had a clear view of the tense moment.

Footage shared on social media shows the pair drop to the turf and look back to check fans in the lower tier are able to see the action.
