Villas-Boas? If you want to progress, then I wouldn't suggest it. He isn't ready yet.
Even though the Chelsea players were disdainful, flippant and ill-mannered toward him, he didn't do himself any favours. He couldn't handle the media exposure and when asked a question, he always felt that there was a vendetta against him and took everything personally. He couldn't handle the dressing room, coupled with being poor with man management.
I don't really agree with the manner in how the Chelsea players revolted and what they said to Villas-Boas, but he tried to implement a philosophy & style of football that Chelsea did not have the players for. Each game he set-up the same way and Chelsea were becoming easier to beat/nullify - players who couldn't be bothered, playing a system which didn't suit Chelsea's game and not working to the team's strengths - there was only going to be one outcome in the grand scheme of things. I think the players were trying to tell Villas-Boas to not use the free-flowing, fluent football that he wanted to bring to Chelsea because they did not have the personnel for it. Villas-Boas may have reacted quite angrily and so the players just took matters into their own hands.
Not nice to see and disappointing behavior from the senior players at Chelsea, but with the constant change of manager virtually each season, what would you expect? Prima Donnas.
Spurs do have the personnel to fit Villas-Boas's philosophy, but say if you got him and things aren't panning out and if the team selections are wrong or whatever, it will be interesting to see what Villas-Boas does to try and rectify it. Will the pressure get to him again? Will the fans get on his back? Would the players rebel? Also, what about his man management with the players? Will it be better or worse than Harry's? Man management appeared to play a pivotal part in Spurs getting as high as 3rd in the first place, so how would AvB do? Would he handle the media better than he did previously in England?
I personally don't feel he's ready yet for any top Premier League club and the experience at Chelsea was a learning curve, but if AvB has any common sense, he would try out other teams like Inter Milan or Sevilla or somewhere like that, before he comes back to the Premier League. Going from Porto to Chelsea was always going to be a massive task.
