Levy (and many fans) main problem with Harry was ALWAYS longevity, and his own personal ambition... DESPITE what Harry says out the car windaaa, he ALWAYS wanted - and no doubt assumed - he was a shoe-in for England at SOME point...
...the fact he was overlooked isn't our problem, it's most definitely his... but it doesn't change the fact that in his mind, he wasn't going to be at Spurs for the long-run, so investing time in the Youth set-up (only for the inevitable next manager to reap the benefits from) was NEVER going to be in Harry's interests... he was very much for the 'now' (hence some of the signings) and to be perfectly fair, the 'now' has been pretty good, let's not kid ourselves.
But there's no use us being a one-season wonder every 10 years or so, we need to build from the foundations up... hence the new training facilities, and hopefully, the new ground.
Levy knows this, and has made provisions for this... Harry didn't, and probably couldn't care one jot WHERE or how GOOD the new training ground was, as long as the tea-lady made a 'triffic brew!
Levy is restructuring the club from top to bottom, to focus on the FUTURE... and good job too. We've been in 'transition' for too fudging long, after a succession of 'Me-Me-Me' managers (Jol aside) who were never going to weave themselves into the fabric of the Club... AVB just might be someone that can!
