Agreed, but there’s a fine line between damaging a young players confidence by playing him out of position, and we playing him where he can establish himself.He's clearly much better there, but needs must, and we don't have too many wide attacking options at present. When/if Enciso, Welbeck and Fati are back up and running, there's going to be a lot of competition for just two attacking central positions. Note also that Mitoma and Adingra are off for a while in Jan.
All I'm saying is that, rather than just focusing on where he plays best, we also need to factor in where there are gaps for him to play as many minutes as possible (which is what he'll ultimately want I suspect).
Hinshelwood is a clear exception to the above though.
