I agree we played more narrow with Potter. Without a doubt. Players were positionally and tactically free to do more whatever they want, and when a ball-loving player gets frustrated, they wander inside. For good and bad. Trossard in particular is a lot better with the ball than without it - and maybe he would have been better sooner if Potter gave him more strict instructions.It may look like that but it wasn’t the case IMO. Trossard liked to receive the ball and cut in, we never really made the pitch big in that respect. That was an area that RdZ really improved.
With Roberto De Zerbi, width was key. I honestly don't think he's spent many nights pondering what to do if the wingers are shit. They need to be dangerous. We had ONE attacking game plan: do a rondo between CB and DMCs and when the opponents full back come in to support the pressure, play it behind them; the wingers are then free to do as they please. This is what we based our entire attacking play on.
Potter wants players close to each other, collaborating, switching roles and finding solutions. Roberto De Zerbi wants the super narrow-super wide team that look like they mess around in the middle but then quickly punch you in the face through abusing the spaces you forgot about. Different philosophies and no one objectively better than the other.
To the players... different things work. It didn't take 180 minutes before we saw Trossard mouthing off with De Zerbi, seemingly about petty micromanagement. Some of our players thrive with being told exactly what to do and others like Tross felt it was limiting.
Potter, in general, throughout his years in Östersund and Swansea, wanted pacy wingers with imagination. I do believe that if had access to more of that, no one would claim "Potter doesn't like wingers", regardles of other criticism they might have. The fact that we played more narrow with Potter than with De Zerbi is probably down to the choice of playing someone like Jahanbaksh instead of Gross or Lallana. We did not have a particularly impressive set of wingers for most of the Potter era.
