Problem we had with Ireland when he first came in, was that nobody seemed to have any idea where he played. Starting him at Newcastle in the middle, and a couple of other games too, was completely bizarre, and wouldn't have helped his confidence, especially when he got dropped.
I think if he keeps on improving, then he will be at least a £15m player. Not only is he recreating what he did at City, but it seems he actually wants to do more... Tracking back, tackling etc... trying hard for the team in general.
A player like that who tries hard, with the talent he has, is an extremely valuable type of player to have in your side.
