People should chill a little, him playing as a forward is at least partially because we have very few forwards in the travelling squad. He's a talented player still finding his feet in the game, plenty of time for him to find his best position. Grealish was mostly playing as an 8 until his early 20s before establishing himself on the left wing, even a talent like Foden has broke through at City in forward positions whilst being earmarked for centre midfield. Modric, Bernardo Silva, David Silva too started out wide. Its fairly normal for that kind of playmaker. Some stay as wide men like Joe Cole, Mata, Beckham. Others revert centrally as they mature. Central midfield is the hardest position to play, for technically excellent young players it's sometimes harder for them to adapt at first team level because they need to learn when to keep it simple, when to be disciplined, when to move it quickly, whereas at age group football they've been accustomed to waltzing past the opposition when in dangerous situations because they were so far ahead ability wise. So playing further forwards allows them more freedom.
