AVB's always been a great tactician and good manager, just poor at handling egos. It showed at Chelsea, but I think Spurs may be the perfect club for him - they've flattered to deceive too much in the last few years (decades?!) to have problems with egos in the squad. Wouldn't be surprised if he led them to a decent title challenge and CL run next season, but then faded away in following years as the players start letting the successes go to their head and he struggles to rein them in again.
I think your jumping the gun abit here, I think it's unfair to judge any manager by what goes on at Chelsea.
AVB has a good philosophy on how football should be played, and Chelsea for years have played in a somewhat defensive manner. Which was started under Mourinho.
AVB was trying to get them to play in a more expansive manner, playing a very high line, pressing the opposition, and after a few bad results playing that way, the Chelsea players rather than stick with it lost faith in the manager, and clearly weren't giving there best for the manager on the field.
Spurs got off to a slow start this season, playing AVBs way, but they stuck with the manager and gave there best for him and now there seeing good results, as the team is now beginning to master his philosophy.
Chelsea were also a very old experienced team, so maybe AVBs age counted against him a little, as he was younger than some of his players. So some of them maybe didn't respect his standing in the game, in the same way they respected Ancelotti
