For me, who followed with admiration his work at Porto between 2002/2004, without being my club, the amount of people this guy inspired in Portugal to become a football coach, to start studying football at Universities and so on, it's really painfull to watch how low his current level is. It's not only the usual downfall you see from top managers who were 10 maybe 15 years at the top, excluding Ferguson, Trappatoni, Lobanovsky and a few more.
You can look at guys like Wenger or Benitez recently, or even Ancelotti, but not one of them looked so miserable talking about the game, we already know how it will end, the only thing we know is that Mendes or maybe other agents really show how it's possible to keep working at this level even if everybody who has a reasonable understanding of the game know that he simply won't change, doesn't want to reinvent himself, and even the things where he made the difference, like the mental side of the players, or being strong regarding the deffensive organization of his teams, it's all gone.
I even doubt if he had the best squad in Portugal he would win the League, that's how bad he is. And this is the same guy who a few months ago was saying Bruno Fernandes would struggle in England and at the same time brought Gedson Fernandes to Spurs. Go figure. My advice to Spurs, send him home and don't start next season with him. Really, forget it.
