Former Arsenal star, Ian Wright has pinpointed the big mistake the Gunners made during their Premier League 2-1 defeat to Aston Villa on Sunday.
Recall that Matty Cash gave Unai Emerys side the lead before Leandro Trossard equalized for Arsenal.
But a late second-half goal from Emi Buendia gave the hosts the victory against Mikel Artetas side at Villa Park.
