I don't see how this doesn't affect Foden and his playing on the wing far more than he wants. If he finds himself on the wing this season, he has every right to be pissed.
Can you imagine Pep putting a player who was bought for 100M and had just won Player of the Year the season in his preferred position back in a position that he doesn't want to play and is clearly worse at? I can't.
I can definitely imagine Pep doing that. He played Bernardo Silva left back.
