David Dein has stated that he does not see a clear replacement for Arsene Wenger at the Emirates Stadium.
Wenger has now been in charge of Arsenal for 20 years and the Frenchman will arguably go down in history as one of the club's greatest ever managers, if not the best.
Despite all his achievements at Arsenal, a lack of trophies in recent times has led to many calling for the 66-year-old to step down from his role but former Gunners chairman Dein does not think that there is anyone available at the moment who could do a better job on the red side of North London than Wenger.
Dein told talkSPORT: "Everybody has their own opinions. But it's very difficult because the next question is who would you want as a successor – and that's where the conversation stops.
"Today in football you don't see anybody staying – at least for 20 years – and two things I'm certain about when it comes to his successor are, one, he won't get his team into the Champions League for 20 successive seasons and, secondly, he will not be there for 20 years in any event because the longevity is about 15 months at the moment."
