Not sure Leon is a forceful enough character - in fact I'd go so far as to say he's definitely not. The captaincy shouldn't be awarded on length of employment.
I'm not Chico's biggest fan but the captaincy could be the making of him you know. However, I don't think his English is that great.
Shelvey has emotonal issues and hasn't got the experience or the cool head required.
Looks like it'll be Rangel's by default.
Leon is the heartbeat of the team and leads by example on the pitch, whereas Chico is embarrassing with his cheating at times and a liability at other times.
