I never thought he was a winger as such, in the 4231 the player is a forward, but I call them a winger, there arent many real wingers left anymore, I mean for me I still consider Messi and CR7 wingers in a way.
But yeah hes a forward, I didnt think he was effective as a number 9 up top on his own, so thought him playing as a "winger" would suit him more due to his good defensive work.
I mean we might still play a 433 at some point, so in that case for me hes a winger.
Just explaining my use of the word winger.
His ability to score goals I have never questioned and it was always a case of finding his best position, which I think we now have.
