what you using? is it the 10.3 patch or an updated database?? like the summer one??
cause he has never been this good in any of the official patches, I have seen him a couple of times
10.3 patch, The reason you dont see him improve so much is because he has not signed a team that has good facilities, Give him the good proper training and he becomes a viable player.
