After weathering the early storm, Betis took the lead when Rodrigo Riquelme was left unmarked at the back post for a simple tap-in after Kepa Arrizabalaga had fumbled at a corner. If the Arsenal goalkeeper was at fault for Betis’ opener, there was nothing he could do about their second. Nelson Deossa was afforded far too much space just outside the area and unleashed an unstoppable effort into the top corner.
