Arsenal's Emirates homecoming was spoilt on Wednesday night as a Villarreal side boasting a couple of former Gunners ran out 3-2 winners in north London.
Nicolas Pepe and Denis Suarez, who made just six appearances for the club during a 2019 loan spell, were involved in a couple of the goals for the LaLiga side.
The former bagged the 16th-minute opener before Karl Etta Eyong doubled Villarreal's advantage just after the half hour. New Gunners signing Christian Norgaard halved the deficit before the break.
Suarez then provided the pinpoint pass that allowed former Tottenham forward Arnaut Danjuma to restore the Spanish side's two-goal advantage.
