Boxer Tyson Fury has placed a £200,000 bet that he will become World Heavyweight Champion.
His uncle and trainer Peter Fury said the private bet was made with “a wealthy relative”.
Should Morecambe-based Fury defeat reigning champion Wladimir Klitschko in Germany on November 28, the bet could net him £400,000.
Peter said the amount Tyson could earn from the fight itself could be “between £4m and £5m”.
“The two of them have had a sportsman’s bet...£200,000 each,” said Peter.
“If he wins, Tyson takes £400,000.”
Fury, 27, is in training ahead of the clash in Dusseldorf for the WBA, IBF, WBO, IBO and Ring Magazine World Heavyweight Titles, to be shown live on Sky Box Office.
Ukrainian Klitschko, 39, hasn’t lost a fight for 11 years and is the betting favourite.
But undefeated Fury, who lives in Hest Bank, has shown unwavering confidence in the run-up to the bout.
And he appears to be in the best physical shape of his career.
In an interview with the BBC earlier this week, the brash boxer compared himself with the legendary Muhammad Ali.
“I’d say I’m a modern-day Muhammad Ali,” said Fury.
“I’m not trying to be him. I don’t want to be any man, only myself.
“I don’t think there’s anyone like me in boxing. I do some crazy stuff and I’ll continue to do it, if it puts a smile on people’s face.”
Tyson also recently said he wants to become MP for Morecambe and showed up for a press conference with Klitschko dressed as Batman.
