Former Arsenal boss Arsene Wenger is refusing to visit Emirates stadium to see his statue unveiled.
The creation of an artistic tribute to ex-manager Wenger is at an advanced stage.
But David Dein, who used to be Gunners vice-chairman, claims the Frenchman is yet to give the green light to a ceremony because he is still upset by the way he was forced out in 2018.
Dein told fans at an Arsenal Supporters' Trust event: “Rather like myself, he is bruised. I don't think he was treated well.
“I think he is still smarting from that. He was never really given the opportunity to discuss an alternative role at the club.
“That caused friction. There was also interference from board members in what he was doing.
“He had a difficult time. I do hope that he does come back.
“It's no secret, there is a statue waiting for him to be unveiled. I hope he does decide to do that. For what he delivered to the club, he certainly deserves it.
“I know he is in two minds. He hasn't agreed to do it yet. I'm pushing him to try and encourage him that he should.
“It ought to be there, a permanent memory to what he delivered to the club."
