He then ploughed his lucrative earnings into a stunning £19million mansion in Beverly Hills to kick back, relax, and reflect on a truly remarkable career in the sport.
And the latest sneak peak into his Californian crib has revealed an enviable wine collection.

‘Money’ flaunted on Instagram 15 rows of wine stacked perhaps 15 bottles deep, captioning the image: ‘Like fine wine.’
Mayweather wasted no time splashing his $100million (£77.6m) earnings from the super-fight – though that could rise to as high as $350m (£271m).
The Mayweather mansion has an Italy-imported gourmet kitchen, dual-bath master suite (complete with a treetop terrace), black-and-white marble pool deck, a guesthouse, a living room with 10 sets floor-to-ceiling French doors and an ebony-panelled library to go with the wine cellar.
It appears Mayweather will have more benefits than most when it comes to home comforts in retirement.
