I think is too much a British orientated list there, like you haven't included some very important managers there like Pozzo, Capello, Rocco or Trapattoni, managers that not only built very successful teams, but also showed fantastical tactical skills, even moved the game forward greatly in how it is played tactically now. Where as I don't think you can say that of quite a few on that list, who put together great sides, and motivated them well, but can't really be said to have left a tactical legacy like the great Italian managers have. For me its Nereo Rocco, not the inventor of catenaccio, but certainly its prime advocate. I don't think there is any manager that has had more impact on making successful sides through their organisational and tactical ideas than he has had.
