Derek Chisora has vowed to get his career back on track by beating fellow Londoner Larry Olubamiwo at Wembley Arena on Saturday night.

The former British and Commonwealth heavyweight champion returns after losing his titles to Tyson Fury on points in July.

"I'm not even talking or thinking about a loss. I'm winning this fight no matter what," insisted Chisora, 14-1.

"My future in this sport all hangs on next Saturday night and I've got to completely destroy Olubamiwo.

"It's the brutal truth, I've got to win to get in a position to get my British and Commonwealth belts back.

"Nothing else matters apart from winning and I'm going to knock Olubamiwo clean out.

"It's going to be a major statement from me that I'm back and I mean business."
