Dereck Chisora today put the final touches to his WBO/IBF world title challenge against Wladimir Klitschko in Germany next weekend.
Del Boy performed a brief work out for the media at his gym in Finchley before declaring himself in the shape of his career.
The 26-year-old takes on the younger of the Klitschko brothers in Mannheim in the toughest challenge of his career.
And he promised to put in a better display than Britain's last heavyweight title challenger, Audley Harrison.
"I still can't believe the way that Harrison fought," said Del Boy.
"It was pathetic. If I perform like that against Klitschko, I'll never show my face again in the UK.
"I had a great training camp in Scotland, and I've just been putting the finishing touches here in London. I'm ready and I can't wait."
Earlier this week, speaking to Golzka, Chisora added: "I am in excellent shape.
"On December 11 I'm going to prove that Klitschko made a big mistake by choosing me as an opponent. You have to know how to fight him, like Corrie Sanders clearly demonstrated. He took Klitschko out and I'm going to do the same to Wladimir.
"I'm not going to play by Klitschko's rules. To exchange punches with him at a distance - it's not for me. I'm going right through his protection to chop him down.
"It will be very spectacular for the audience. When I get to Wladimir's jaw, he will fall, but he won't get up.
"On the evening of December 11, all of Klitschko's fans will suffer inconsolable grief. There will be a new champ."
"The heavyweight game used to be the mother of all sports. It's gone down - the Americans ain't producing nothing, the Klitschkos have made the sport boring so there's no-one out there - except for Dereck Chisora. I'm here to save boxing."
