The question is whether Foden is the best player we have in that position. If Cherki is a better 10, why play Foden there? Foden hasn't been the best at creating chances. Over the last 3 seasons he has fewer than 10 assists for Haaland. Even in his best season, 23/24, he didn't have many assists. He was more of a second striker.
Fans want to fit in all players they like regardless of team balance. IF Cherki is a better 10, then Foden gets in the team as an 8 or on the wing (but more as a midfielder than a pure winger). To be a proper 8, he needs to be able to run a lot and win duels in midfield. He will fit more naturally on the wing right now.
Cherki needs to prove he's the better player in the 10 role. He looks more natural there but he needs to show his quality in the PL and the CL. It's Foden's role for now.
