growled: “I’m cool. I’ll strap up the boots and tie up the gloves one last time before I’ll say ‘f*** it, let’s go!’

“There’s no plan A, B or C with me. Tomorrow night I am willing to die in that ring. I am just buzzing. I am excited.”

Del Boy made his 2007 debut at 17st 7lbs and melted down to 16st 11lbs for a pair of 2013 tune-ups.

But his best and most recent wins have come just north of 18st.

Wilder closed the show, saying: “This is my time.

“I am not affected by mindgames, I knew Derek would try to make me laugh or scare me.

“But I’m a fighter, same as him, so none of that matters.

“I believe what he says, he said he’s going to retire, he made his wife a problem and, like me, he’s a family man.”
