His temperament is questionable, but I would argue that with Adams as manager, and senior players such as Brittain, Tokely, Munro, etc in the squad, there is more leadership than at previous clubs - especially hibs where they have been lacking leadership for a long time now.
If we sign them we can only speculate as to whether he can be controlled, and whether he can perform, but we have to try something to get a bit of creativity in the team. He's got that little bit about him and has the talent to do what he wants on the pitch (it's about whether he really wants to or not).
