Ainsley Maitland-Niles had a night to forget as his own goal and a Luis Suarez volley helped Barcelona to a 2-1 victory over Arsenal in the Joan Gamper Trophy.
Pierre-Emerick Aubameyang looked to have teed himself and the Gunners up for the new Premier League season in style with a fine first-half goal but Barcelona pressed in search of an error that eventually arrived when Maitland-Niles put through his own net.
It was a cruel moment for the 21-year-old in front of a huge Camp Nou crowd and Arsenal boss Unai Emery could have done without having his defender’s confidence dented with a Premier League season opener against Newcastle United just six days away.
