Agree with this on the whole - I think what might end up becoming an issue with him is if we are relying on our full backs for attacking width, he doesn't seem like he has *that* much about him.
He uses the ball well and I don't have any real issues with him defensively - in fact I'd say he's a step up from Digne in that regard. Has better recovery pace and is more tenacious. If we persist with 343 next season though, I can eventually see him being an issue as a wing back. As a conventional full back though, I think he's absolutely fine from what we've seen. Still think we need to buy an actual left back as cover though - Kenny 100% is not enough on this and we know nothing about how the club view Nkounkou
