A packed card will see the best of British boxing talent on show at The O2 , Greenwich, on Saturday (December 12) but there’s no disputing which clash is top of the bill.

Anthony Joshua takes on Dillian Whyte for the British heavyweight and WBC International and Commonwealth Heavyweight titles – old foes in their amateur days.

Joshua and two others featuring on Saturday – Chris Eubank Jnr and Kevin Mitchell – took part in a public workout at the Reebok Sports Club at Canary Wharf on Monday (December 7) to show how their preparations were going.

Joshua, who has never had to go beyond the third round in his 14 professional fights, is confident he will take the vacant British title and plans to take out Whyte early.

He said: “We’re going to go to war Saturday. All the verbals are irrelevant to me. I do my bit in the ring. In the press conference, let them do the talking. I turn up Saturday and that’s when I want to do what I do.”

There is bad blood also between Eubank and his opponent Gary O’Sullivan. Eubank said: “For me boxing isn’t a personal thing, it’s a business, it’s a sport, it’s something that I do because I love the sport. For him, he’s used social media, Twitter, Facebook to be extremely disrespectful towards me.

"That’s why it’s a grudge match, that’s why I’m putting so much training and effort into this one – because this guy needs to be punished for what he said.

East Londoner Mitchell fights Colombian Ismael Barroso for the vacant WBA Interim lightweight title. He missed out on a chance to take the WBC lightweight title when he was beaten in the 10th in May.

He said: “As a kid, winning that world championship is what I’ve dreamed of. I was seconds away from being world champion. The way I look at it now, I’m world champion without the belt and next year I’m going to clean up the division.”

The evening – Bad Intentions – will be shown on Sky Sports Box Office .
