Granted Wenger was a hypocritical mong about the whole affair but he rejected the chance to become a full time coach of the U18's with us, instead wanting to preserve his cushy Sky Sports gig. He could have worked his way up the ladder at the club, putting in the hours plying his trade and learning from his mistakes but he made his decision.
A part time gig spending a few hours a month (if that) with the Belgium National team isn't at all comparable to what both Vieira did (full time behind the scenes at City & now manager at NYFC) and Arteta is currently in the processing of doing. Pep spent years behind the scenes at Barca working with the Youth Team before getting his chance at Barca.
Fair enough, I don't begrudge him for choosing the easier and more lucrative option of preserving his role in the media but he can't expect to be seriously considered for any top job as it stands and until he demonstrates his full commitment to the cause.
