His hold up play used to be OK, he's always been sloppy when his mind wanders but for the first year/year and a half he was fine even if it wasn't quite enough to warrant a place in the side when he wasn't scoring. For a while he's looked absolutely useless though, he no longer looks capable of creating something out of nothing either, he's effectively Darren Bent which 3 years ago I'd have barked at the comparison.
Hopefully it's all mental and he can sort it out, I do miss unplayable Cisse.
