Emile Smith Rowe scored his third goal in as many league matches as Arsenal moved up to fifth with a 1-0 win against Watford.
Pierre-Emerick Aubameyang had seen a first-half penalty saved by Ben Foster on the veteran goalkeeper’s 500th career appearance, after a Bukayo Saka effort was ruled out by VAR for offside.
But the Gunners went ahead in the 56th minute when Smith Rowe struck a first-time shot into the bottom-right corner after the ball had fallen kindly for him just outside the area.
Joshua King came close to an equaliser for visitors Watford, who finished the game with 10 men after Juraj Kucka was shown a second yellow card in the dying moments.
Smith Rowe, the England Under-21 international who was this week omitted from Gareth Southgate's latest senior squad, now has five goals in his last eight games in all competitions for Arsenal under Mikel Arteta.
