Starts with a 60 rating on Fifa which wouldn't even get him into the Hibs midfield! Pretty sure if you train him and give him game time he will hit the mid 80's though, not without hard work. I haven't played Football Manager this year so you would need to ask someone else about him, that game factors in injuries and form pretty harshly though, but I imagine you could turn him into a good player due just to his young age.
Just had a look and his potential ability on FM is between 140-170, so he has the potential to be a good player on FM but he needs the work put in. Lots of game time and training and he can potentially be a very good squad player, but never a star player in a top team.
I'm happy for games to underrate our players though, as frustrating as it may be when you want to use them in said games, it also lets them grow and develop without as much pressure as say Freddy Adu, who everyone expected to be the next big thing.
Plus it's just a video game.
