Dein brought Wenger to Arsenal 999 games ago.
"Heâ€™s a football purist and this is his life. Heâ€™s still got the fire in his belly. He is a workaholic. I can understand people being anxious about not winning trophies, but nobody more than Arsene himself."
And Wengerâ€™s legacy to Arsenal?
"It will be five-fold," says Dein to the Telegraph.
"Wonderful new training facilities. A new stadium. A new style of football. More money in the bank that at any time in the club's history. And recognition and respect for Arsenal that spans the entire globe. Thatâ€™s not a bad list for his CV."
