Bielsa.
Reasons in no particular order:
a) I don't know much about managers to be honest
b) even though he's got that crazy rep, I'm not sure it would be crazier than promoting a coach with zero first team experience (pep), his assistant (tito), a coach with no experience in europe (tata) or our very own Lucho
c) the guy really impressed me at Marseille, I had this feeling he'd do well and like everyone i like being right
d) His main qualities are definitely an attractive brand of attacking football with lots and lots of pressing and dynamism.
e) He would scare the shit out of our board (the current one).
Which is why I don't think they'll go for him. Or maybe. As a mea culpa move.
