I agree: Cech would be the obvious captain, but having the captain be the keeper, makes 0 sense as they can't leave goal to sort things out, and it just doesn't help the team that much. Cahill isn't a regular starter, and i am still not keen on him being captain. Ash would be short term. Mata just seems to quiet. He rarely will get in someones face and give them an earful and i can't see him bossing anyone around. Mikel... Not for me Luiz is young has great potential, can be a fixture in the squad for a long period of time, is very likeable to the fans, is respected by the players, and would be a suitable choice. He isn't exactly a John Terry, but who is.
