Not sure it’s that to be honest. It’s basically a technical ability, you can either do it or you can’t. You can improve obviously, but you shouldn’t be awful at crossing just because you didn’t used to do it a lot, it’s using the same skills as passing/shooting really so it shouldn’t take 12 months of practicing. I think he’s just a really hit and miss kind of player, he does some great things (including crossing) but then some awful things. He has an alarming habit of playing loose passes right into the middle of the pitch for example. He’s very inconsistent, that’s the issue.
