Floyd Mayweather Jr's Instagram account provides a fascinating insight into the life of a world-champion boxer.

Often described as the world's best pound-for-pound fighter, the multi-millionaire athlete is not afraid to hide his obsession with wealth. Nicknamed 'Money', Mayweather regularly posts pictures of himself with extravagant purchases and outlandish mounds of cash.

Unless you've been living under a rock, you know he is set to fight UFC star Conor Mcgregor later this month which is estimated to fetch the boxer a cool $300 million.
