After three consecutive league defeats, Arsenal bounced back and prevailed over Watford 3-0 in an English Premier League (EPL) game that saw the Gunners' German midfielder Ozil reach a career milestone.
After losing to Tottenham Hostpur, Mancester City and Brighton & Hove Albion, Arsenal got back on track with a 2-0 win over Milan in the first leg of the Europa League round of 16, and it maintained its momentum against Watford.
Arsenal took an early lead in the eighth minute on Shkodran Mustafi's header off a cross by Ozil, who reached 50 assists in a record 141 EPL matches.
This was two fewer matches than it took former French player Eric Cantona to get over the 50-assist threshold.
Watford rarely threatened Arsenal's goal during the first 45 minutes with Roberto Pereyra squandering the visitors' closest scoring chance.
After the intermission, Arsenal doubled the score just when Watford was dominating, as Pierre-Emerick Aubameyang made the most of Henrikh Mkhitaryan's nice through shot in the 59th minute.
Just two minutes later, Watford had a chance to get on the board when the official awarded Pereyra a penalty after being fouled by Ainsley Maitland-Niles, although Troy Deeny missed on it.
On a counterattack, it was Mkhitaryan who secured the Arsenal win with 13 minutes to go before stoppage time.
After the victory, Arsenal is in sixth place with 48 points, while Watford sits on 10th with 36 points.
