Clarke believes that the section of Arsenal fans calling for the head of Wenger are the noisy minority.
"Most people at Arsenal would say he has done a great job there,'' he said. "If he has a season that is a little bit more disappointing than other seasons, then surely they are going to stick by him and see it through.
"Yes, there's a chance they won't qualify for the Champions League, but that also applies to big clubs like Chelsea and Spurs as well.
"You've got a lot of big teams who spend a lot of money and want to finish in the top four but not everyone can."
