Right now he’s as good going forward as Chamberlain. The only issue with him at wingback is whether he can defend well enough, which was also an issue with Chamberlain.
In the central roles he won’t have enough time on the ball and he’ll be bullied. Putting an inexperienced pacey player out wide has always been the best way to give them an education.
Oh and the fact that you’re dropping 1 of Alexis/Ozil to accomodate him, not happening. If we play a front 4 instead of a front 3 then fair enough though.
