Former Arsenal captain Gilberto Silva can see Patrick Vieira returning to the club.
Vieira is currently in charge of New York City FC.
Gilberto Silva, speaking exclusively to 888sport, said: “It's quite hard to say if it was wrong or not. When he left Arsenal he went to Juventus then Milan and Manchester City.
"I don't know what went wrong for him to be at Manchester City and not Arsenal. He's now starting his career as coach somewhere else to find good experience but there's a possibility he comes back to Arsenal.
"He was a massive story at the club and everyone likes him so this could be something for the future. If he was to come back and work with Arsene and his staff I would be very happy to see that happen."
