Campbell blasted Bellerin for being afraid to tackle.
He told Football Insider: “The debate has been out on Bellerin for a while now. His defensive qualities come into question against the big teams.
“I am yet to see a dominant full-back display from Bellerin. I know he is very good going forward but I do not see him as a defender. He is a converted winger.
“As a full-back, your first job is to defend and let's not even talk about the foul throws. It is getting ridiculous. He is a professional footballer. It is not on."
