Barcelona B who play in the Spanish equivalent of the Championship, and Maccabi Haifa. For me the only question mark is whether he is a good man manager and things along those lines, I'd be confident in his tactics and ability to attract quality players from what we know of him.
Much more exciting than a Warnock or a Bruce or a Holloway. Was 2nd favourite to take the Barca job when Pep left. Clearly has a lot of playing/coaching experience of the very best football tactics in the world. I think he's qualified enough, somehow.
