Clrnc there's clearly some truth to what he's saying. That being said, can't dispute that Spurs are much more serious force now than they were during his time (just still not serious enough) - regardless of club loyalties, Levy is probably significantly responsible for that.
The challenge now though is that they face a very tough period of paying off a stadium without CL football for who knows how long. That could undo all the progress they've made (fingers crossed).
They probably do need a manager who through force of will can reshape the club culture like Arteta did. Not an easy job and I have no idea whether Ange would be capable of that (even if the intent is there).
