I don't want to undermine our current captain, but from the majority of the posts on here (And my own opinion), Kolo will not in the first choice back 4.
This means he can't really be the captain, so who will take on the mantel of captain?
I'd say Kompany (As i did at the beginning of this season). He has been with us for 2 season, so is not a new comer. He has, for me, been one of our top performers, and i haven't seen him have a really bad game, showing his consistency.
He also seems to be a great professional, and haven't heard of him talking in the press.
I love Kompany, and hope he stays with us for the rest of his career. To have him captain for a long time would be the right choice.
Vice would be Barry, as he is always in the team, and is a consummate pro.
