The more I think about it, the more obvious it is.
Barry Ferguson.
Probably has played more games than anyone else (exp. maybe Digger) at a consistantly high standard.
One of the most coveted CB's in the business. Maybe hasn't scored much but some of his performances have been top drawer and there is no point in scoring if your conceeding the other end. He organises that line and is always barking out the orders. He's a real captain fantastic.
