@Eden17 Imo, I think Hazard is a passionate guys and make every sentiment stronger, for exemple, if he is in a good set of mind he will perform way better however, if he is having problem with his manager, injury, etc... I think he is the kind of player who can become inconsistent. Anyway, I feel he doesn't have the good mentality to be a captain imo, but it might be for the best, as his personality and disposition can propably uplift team spirit in a different effect a captain could. Beside, at only 26, he is a bit young to be captain of a team. :)
Our three centre-backs Gary Cahill, David Luiz and Cesar Azpilicueta, along with Cesc Fabregas seem to be the front runners, but Hazard has done it for Belgium as well.
I'd really like Azpi to have it for all that he has done and is for the club. He loves the club, there's no doubt about that having rejected big moves to Barca and Real in the past, he did the job as captain against Spurs last FA Cup semi-final and for me is the first name on the team sheet, and the guy you want on the field for every minute.
Obviously, Cahill looked like the natural successor last year, but Luiz, Eden and Cesc have that leadership too.
