Arsenal hero Bob Wilson fears Arsene Wenger is ready to walk away.

Wenger is reeling after last night's defeat at Bayern Munich.

Wilson, who played more than 200 games for Arsenal and was goalkeeping coach under Wenger before retiring in 2003, told BBC Radio 5 Live: "The big question now is, is this going to tip Arsene over the edge?

"He's a hugely intelligent man; he can only take so much.

"He lives for the club, totally dedicated, very hurt when things go wrong. But as everybody knows and everybody sees now, his longevity in the job, 20 years, seems to be a little bit like a millstone round his neck when things go wrong.

"I wouldn't be at all surprised if Arsene, given the amount of headlines that are coming his way, might just look at that and say enough is enough. I think as a human being you can only take so much."
