Watford came from two goals down to draw 2-2 with Arsenal at Vicarage Road on Sunday in the Premier League.
Pierre-Emerick Aubameyang scored twice in the first half to put the Gunners in charge, but Tom Cleverley capitalised on some abysmal defending to pull one back for Watford just after the restart.
Roberto Pereyra completed the fightback late on with an equaliser from the penalty spot to ensure manager Quique Sanchez Flores picked up a point in his first game since being reappointed Watford boss.
Elsewhere, Everton suffered a second defeat of the season at Bournemouth.
