direct replacements aint a big thing for Pep imo. I have a feeling he will revamp our game this summer, hopefully for the better), no more false 9 system, which served us quite well in the league btw, but I expect much different outlook from fullbacks and the way we play, and yes it could more of a chance of 4231, 4213 with fullbacks having much more attacking tasks down the wing. or at least there will be certain games to go with this plan.
