Boxing legend Floyd Mayweather has reminded fans of his wealth by flaunting the £80million purse he earned from last year's blockbuster win over Manny Pacquiao.

The retired American fighter was also keen to boast about his upturn in fortune yet again in a post uploaded to his Instagram page on Tuesday.

Mayweather defeated Pacquiao by unanimous decision in May 2015 and announced his retirement four months later - after beating Andre Berto - with a 49-0 record still intact.

The 39-year-old wrote on Instagram: 'Gotta love these backseat drivers so worried about another man's legacy instead of trying to write their own. Ultimately, I will always have the last laugh.

'This is just one of my many checks, a cool $100,000,000.00 that I still have every dime of. Y'all still have to work however, I'm happily retired. At the end of the day, it's them Benjamin Franklins that matter to me, so the jokes on you.

'I've made smart investments, sorry for those who thought that I couldn't read, write, or count.

'Y'all call them watches, I call them time pieces. Y'all call them boats, I call them yachts. Y'all call them houses, I call them mansions. Y'all charter jets and we own jets. #TMT.'

Filipino boxing great Pacquiao has left the door open on the possibility of a rematch with Mayweather if the American ever comes out of retirement.

It was a fight which attracted a pay-per-view audience of five million and was one of the most heavily promoted bouts in the history of boxing, with Pacquiao open to doing it all again having recently come out of retirement of his own.

'If he comes back into boxing there is a possibility, but right now we are not talking about or discussing that,' Pacquiao said on a visit to Japan on Saturday.

The 37-year-old ended his own brief retirement earlier this month by taking the WBO welterweight title off American Jessie Vargas in a unanimous points decision.

'I don't know when my career will end,' the southpaw added.

'I realised I felt lonely inside because... I am no longer active in the sport of boxing. I asked myself if I can still fight, and I decided to come back and continue the journey of my career.'
