Lifelong Manchester United fan, Tony Ward, bet his entire inheritance money - R1 158 536 (£55 000) - on rivals Liverpool winning the Premier League.
The 55-year-old, who hails from Bradford, was so confident that Jurgen Klopp's charges would win the title that he bet the money which was left by his late mother.
She died in 2017 at the age of 82.
Ward placed the bet at odds of 4/6 in Liverpool's favour back in October when The Reds were already maintaining a healthy lead from the rest of the chasing pack.
Liverpool were confirmed champions with seven matches remaining two weeks ago and Ward will now walk away with a large amount of money.
Ward's winnings increased by a cool R758 745 (£36 000) for official winnings R1 917 313 (£91 000) and he already knows what he will do with the extra cash.
"Liverpool were always looking like they could win the title. I picked them after a long, long debate," Ward said as quoted by The Sun.
"I would have got my stake back, I think, if the season had been cancelled. But that would have been unfair. Liverpool were that far clear. They only needed six points.
"I fancy a big holiday. The rest is for a rainy day."
He adds: "She (his mother) wouldn't have minded what I did with the money - not at all. She liked a flutter!
"She liked the horses. But I'd give it all back to have my mum still around."
