Arsenal were rescued by two own-goals, the second of which came in stoppage time, to beat last-placed Wolverhampton Wanderers 2-1 and open up a five-point lead at the top of the Premier League.
On a run of just one win in their previous three games, the leaders looked like dropping more points when Tolu Arokodare equalised for Wolves in the 90th minute, canceling out an own-goal by Wolves goalkeeper Sam Johnstone's arm in the 70th.
Then Yerson Mosquera headed into his own net from Bukayo Saka's cross to gift Arsenal the win.
Manchester City will look to close the gap to Arsenal back to two points when they visit Crystal Palace on Sunday.
Wolves, meanwhile, remain rooted to the foot of the table with just two points from 16 games. They are now just one game shy of tying Sheffield United's record of 17 games without a win to start a Premier League season.
