Ok, my bad.
I realise fans would mainly prefer Foden, Bernardo centrally and I can see very good reasons for that, since De Bruyne being back leaves only one other place. I believe the issue is the right sided forward position. Mahrez played there last season mainly and left, Palmer could have filled that void and left and Doku I assume was bought to fill that right sided forward role, but has disappointed on the right and now mainly plays on the left. I think Pep is struggling to know who is best placed on the right and out of all the options Phil fulfills that best.
Personally I would play Haaland and Alvarez as a 2 up front and have an attacking midfield 3 of any 4 from Foden, Bernardo, Grealish, Nunes and De Bruyne.
