Not really, I think you either have ability or you don't.
Lol that's a load of rubbish. Of course he's got ability, he's a professional footballer!!!
Messi has all the ability in the world, would you chuck him in at centre half? I mean you've either got it or you haven't right?!
It's obvious that he has the basic attributes of a centre half. He's big, strong, hard in the tackle, good in the air and fearless.
His positional sense needs some work, he has already improved his decision making and has cut out some of the rash challenges.
Part of the issue is he wants to win every ball and only with experience will that improve. Needs to work on his distribution too, he will never be a ball playing defender, but he can improve in this area.
Tim and his team can work with him and improve him - that's what coaches are for. If he hasn't moved forward in 12-18 months then bin him off for a reasonable fee. No need to chuck him on the scrap heap just yet.
No patience in modern football.
