As a captain for me he's a 10 out of 10. As a player probably a 7 out of 10. His impact on the discipline of the team, the shape that we hold, and general leadership is worth its weight in gold. He is Pulis's proxy on the pitch.
When the time comes for him to take a squad role and then quit playing altogether, I'd love to see him become assistant manager and then groomed to replace Pulis as manager.
