Arsenal defender Hector Bellerin was helpless against Jack Grealish at the weekend.
That is the opinion of Kevin Campbell.
The ex-Gunners attacker believes Bellerin was not entirely at fault for the issue.
Grealish had a free run down the left wing for Villa, where right back Bellerin was meant to keep things tight at the back.
Campbell felt Arsenal did not do enough to protect Bellerin against that threat.
"Arteta was shocked by the performance and the way the team capitulated," Campbell told Football Insider.
"Bellerin is not a good defender and he got exposed against Jack Grealish.
"Grealish had the run of the Emirates down that left-hand side. You have to be able to defend against your winger one-on-one.
"Just getting back into your shape is not enough against ball players like Grealish. Ball players will play it around you and expose you and that is what Grealish and Barkley did. You have to affect the ball.
"Bellerin did not get much help though. You were hoping Rob Holding could but he is still coming back from injury. Ollie Watkins showed that Holding was still rusty."
