Manchester United defeated Arsenal for the first time in as many meetings in the side's 3-2 win against Arsenal.
Cristiano Ronaldo scored his 800th career goal before scoring the game-winning penalty as United came back from a dubious 1-0 deficit from a bizarre opener from Emile-Smith Rowe.
Smith Rowe, with United goalkeeper David de Gea lying on the ground stricken, scored from the edge of the box, despite VAR showing De Gea had been knocked down by his own teammate Fred.
Before halftime, Bruno Fernandes found the back of the net with the equalizer on his 100th appearance for his side and Ronaldo put United ahead with his first goal on the night.
Martin Odegaard evened the playing field, leveling the encounter at 2-2 but the Arsenal midfielder's foul on Fred allowed Ronaldo the opportunity to score what proved to be the winner.
Cristiano Ronaldo, after scoring the brace became the first player in history to score 801 top-level career goals.
He is the all-time top scorer in men's international football, in the Champions League and for Real Madrid.
