Jose Mourinho wasn't happy and I can understand why Arsenal's penalty will split opinion.
Alexandre Lacazette got his shot away — a poorly executed attempt it was, too — and then came the contact from Davinson Sanchez.
The defender was trying to block the ball but the way he flew through Lacazette forced referee Michael Oliver into making his decision.

Mourinho complained afterwards that VAR Paul Tierney 'confirmed the wrong decision'.
