Maybe you were joking but I think you are spot on. Instinctively he's OK, when he has time to think about it, not so good. I still have one major concern about him and that is his ability to play with his head up (i.e. his awareness of other people when he is on the ball). Although its great that he is scoring, I would like to see some assists from him.
I wasn't actually joking, I think he's a lot better when he's not given time to overthink what he's doing. The vast majority of his goals come from good, quick work in the box rather than placed finishes after being given a lot of time, and I also don't think his vision when running with the ball is that good. He can work on it, I'm sure.
Like his assist yesterday? Or his assist against Fulham?
I kind if get the point, but think Jay's direct runs often cause enough problems.
Let's be fair, neither of those are exactly open field creative genius. I'm not sure he intended his assist yesterday, it kind of bounced off him, and his assist against Fulham was flicking on a corner.
