Pierre-Emerick Aubameyang netted twice and Kieran Tierney grabbed his first Gunners goal in an action-packed finale to the league season at Emirates Stadium.
The goalmouth action started after just 34 seconds, when Alexandre Lacazette was bundled over for a penalty, and Aubameyang fired home the spot kick. Kieran Tierney scored his first goal for the club soon afterwards and we were three goals to the good when Aubameyang netted an overhead kick.
But Watford were in no mood to give up their Premier League status without a fight, and got a goal back before half time through a Troy Deeney penalty.
