I say one thing. If he gets injured, we could easily be fucked. No other option to play high up. Would mean changing rhe whole system for a center half or Lewis at right back
There are 2 options
First:
----------------Ederson---------------------
-----Akanji----Ruben-----Gvardiol--------
----------Bernie-----Rodri-------------------
----------Foden-----Reijnders --------------
Matheus-----Haaland-------------Ait-Nouri
Second:
----------------Ederson---------------------
-----Khus------Ruben-----Gvardiol--------
----Akanji/Rico-----Rodri-------------------
----------Foden-----Reijnders --------------
Savio/Bobb-----Haaland-------------Doku
So I think Pep will constantly rotate between these two and there are plenty of options of Matheus is injured or not available.
Savio or Bobb as LW and Khusanov playing as a RCB or RB, while Akanji or Rico play inverted fullback or centre-back.
