Unai Emery’s men looked to be in control of the Premier League clash after Arsenal scored twice in the first half at Vicarage Road.
Pierre-Emerick Aubameyang continued his rich goal-scoring form with two goals in the opening 45 minutes against Watford.
However, Unai Emery’s men produced a poor performance in the second half to allow Watford back into the Premier League clash.
Goals from Tom Cleverley and Roberto Pereyra allowed Watford to rescue a point and deny Arsenal a first win in three outings.
Sokratis Papastathopoulos and David Luiz were both guilty of mistakes to allow Watford to level the scoreline.
Arsenal star Ozil couldn’t hide his disappointment with the north London side’s second-half display.
Ozil wrote on Twitter: “Two points dropped. Annoying second half, in the end we have to settle for a disappointing draw. Let’s try to bounce back soon. Thanks for your support at Vicarage road ❤ #M1Ö”
Arsenal missed out on the chance to go level on points with defending champions Manchester City in second place.
The Gunners find themselves in seventh place in the Premier League table behind Chelsea FC and Manchester United in the race to secure a top-four finish.
Arsenal will make the trip to German side Eintracht Frankfurt in their opening Europa League fixture on Thursday night.
Emery’s side lost 4-1 to Chelsea FC in the Europa League final last term.
