Watford came from behind to steal a draw against a shaky Arsenal side who once again struggled defensively.
After taking a 2-0 lead into the second half, the Gunners capitulated in the final 45 minutes as they allowed Tom Cleverley and Roberto Pereyra to score for the Hornets.
In total, bottom of the table Watford attempted a club-record 31 shots on goal.
Meanwhile, Callum Wilson found the back of the net twice as Bournemouth beat Everton 3-1.
