That's a fair point and I did say I was probably being harsh.
Just looking at the way he plays I'm not sure I see him as a winger.
In the second half they shifted him to the middle and pushed Siggy out wide. Granted that was his first time playing that position in a "competitive" match with his new side, but he went even more AWOL than Siggy had been. While I thought his combo work with Rose down the left side got them both into some good positions that provided outcomes that will only improve the more experience they get.
