Arsenal extended their lead at the top of the Premier League on Saturday when they returned to action against North London rivals, Tottenham.
The host started the game brilliantly with Thomas Partey sending a first time shot into Hugo Lloris’ top right corner.
Harry Kane scored his 100th away Premier League goal from the spot just moments later though, after Gabriel brought down Richarlison in the box.
Arsenal took the lead again just four minutes after the break through Jesus, who pounced on a Hugo Lloris’ spill to poke home from close range.
Emerson Royal got his marching orders late on after he fouled Martinelli before Granit Xhaka drilled in a third for the Gunners who now lead with four points.
