Arsenal pulled off a remarkable victory against Crystal Palace on Monday night, winning 1-0 with 10 men at Selhurst Park.
Martin Odegaard scored the only goal of the game from the penalty spot, after Palace goalkeeper Sam Johnstone brought down Eddie Nketiah in the box.
The Gunners had to play the last 23 minutes with a man down, after Takehiro Tomiyasu received his second yellow card for a foul on Wilfried Zaha.
But Arsenal showed great character and resilience to hold on to their lead and extend their winning streak to four games.
