I wonder...if you don't believe in EV anymore, then you had to sack him last summer.
Sincerely I don't understand the reasons to do it now, in january...with a Barca probably not so brilliant, but first in LaLiga and CL group.
Furthermore the team was with EV (mostly Leo) and there were no great coaches on the market.
Board talked with a lot of coaches before to signed Setien, 61 years, never been on a top team and never got great results (apart a brilliant way of playing with Betis).
I don't know...I have some doubt about the choice and the moment.
Anyway the football is unpredictable...good luck Quique.
