For someone his age he is very good
He has excellent technical ability on the ball and we can all see his physical strength.
His weakness at the moment is letting a wideman twist or turn away from him in tight spaces (as we saw yesterday, and iirc at Brighton)...it's always when a player fools him to think they're coming inside then squirms their way to the byline on his outside.
Also a couple of times I saw him not busting a gut to get back when we were countered. BUT I have tempered my annoyance of this when reflecting on the sheer amount of up and down Ange demands of you, so occasionally, just occasionally you might be on the limit at that moment...blowing out our arse has happened to us all
It would be an interesting exercise to see how he played, and defended as a bog standard LB in a back four. To test his defensive skills/abilities. At face value it looks like he has a bit to learn in this area BUT if most of your defending is done while scampering back the defenders viewpoint is different.
The other point to remember is there are plenty of high level right sided wide men in this league, so the learning curve is tough.
