Watford were relegated from the Premier League on Sunday but went down fighting in a 3-2 loss at Arsenal, almost clawing their way back from a three-goal deficit largely thanks to former Arsenal striker Danny Welbeck.
Arsenal doubled their lead in the 24th minute when Kieran Tierney's shot brushed the arm of Watford midfielder Will Hughes for an own-goal, and Aubameyang poured on the misery 10 minutes later with an unchallenged overhead kick from close range to make it 3-0.
Watford were given hope of a way back into the game shortly before the break when Welbeck, who left Arsenal to join Watford last summer, won a penalty for the visitors after being scythed down by David Luiz.
Welbeck then narrowed the gap further in the 65th minute, tapping home from close range after a cross from Ismaila Sarr.
But the visitors were unable to find another goal.
