What people need to realise is that whilst Biesla inspired managers like Guardiola and Pochettino, both of those amongst others took the basis of his high pressing game and TWEAKED it.
Basically Biesla (like Martinez) adapts the purest forms of their philosophy with little in terms of a plan B.
my own personal opinion is that he would be a bad appointment, his temperament and stubbornness may have us as frustrated as we currently are under Roberto, alongside the fact the bloke hasn't won any trophies in the game.
If we don't go for a top manager like Mourinho or Emery then we really do need to aim for a Mancini or Pellegrini.
Are you available? I bet you are good on football manager.
