Frankie Gavin says seeing former amateur team-mate James DeGale win a world title last weekend has cemented his belief he can take Kell Brook's IBF welterweight crown on Saturday night.

Gavin steps in against the undefeated Brook at the London O2 Arena - live on Sky Sports Box Office - on a night that also sees Kevin Mitchell and Lee Selby fight for world titles along with a heavyweight showdown between Anthony Joshua and Kevin Johnson.

Former Olympic champion DeGale defeated Andre Dirrell on points in Boston to become IBF super-middleweight champion on Saturday night and Gavin, who is Britain's only ever world amateur champion, is hoping to emulate the Londoner.

The 29-year-old said: "James DeGale did it at the weekend and he was in the same Olympic squad as me so that's given me big belief that I can do it as well.

"I can't wait really. I said it all along. The build-up has gone so quick. Everything's gone to plan. I'd like to thank Eddie because a world title shot looked a long shot last year.

"I'd like to thank Kell for giving me the opportunity. I've traned hard, pushed myself to places I've never been and I'm ready for a world title. I'd like to thank everyone for supporting me.

"No disrespect to Kell because I think he's a great fighter and there aren't many weaknesses in him, but on my day I am up there with the best in the world. When I get everything right, which I have done in camp and sparring, I believe I can be the world champion. Definitely.

"It can't get any better. It's the biggest thing in boxing, winning a world title. Kell's done it so respect to him for that. He's given me the opportunity to take the belt off him so I want to grab it with both hands and come out of there world champion."
