Yeah, I do think that's a problem for him.I still don't know what to make of him. He's clearly a very talented player but I think he struggles for a position, at least in a system that most of the top sides play. I'm not sure he's quick or direct enough to play as an out and out forward and I don't see him in a midfield 3. There's a lot of talk about him moving on this summer but I just don't see where he goes. The role at Palace just seems perfect for him and there's only really Chelsea (and they've got Palmer there) and Utd (who are seemingly in for Cunha) who play systems that you can see him working in. I could for example see where he gets into our side - he's not playing wide in attack for us and I'm not sure he's enough of a midfielder to play in Szobo's role. Same story at Arsenal and probably City, although Pep might be more inclined to play him as a midfielder.
I think 3-4 years ago he could have been moulded into more of a Wijnaldum style midfielder - decently physical and completely press resistant. But I think he's probably past such a major switch of roles now.
He'd be an incredible option off the bench for a top side, but I agree that he may well move and struggle to hold down a starting place. It's the same problem that so many number 10s have had (Ozil, Isco, even arguably Foden who is unbelievable but not a nailed starter).
