Klitschko manager backs Chisora ban

Bernd Boenter, manager of the Klitschko brothers, backs the ban imposed on Dereck Chisora following his brawl with David Haye at the post-fight press conference.

Speaking to BBC World Service, Boenter believes Chisora "needs help" but refuses to rule out a future fight against Vitali, the younger of the two brothers.
