We are just two days away from the fight of the decade.Floyd Mayweather and Conor McGregor will meet in Las Vegas on Saturday night to settle their feud once and for all in the boxing ring.Both fighters believe they will reign supreme at the T-Mobile Arena, of course, with Mayweather reportedly considering betting $5 million on himself.The 40-year-old is known for his gambling and was recently weighing up "putting the most I've ever done at the sports book".In response, McGregor accused Mayweather of having a problem on Wednesday night, saying: "He needs to let that gambling go - he's a bit heavy on that gambling."He's always talking about doing it and then not doing it. I don't really care. You don't really see many winners in those types of places."I certainly know he has a big-time gambling problem, from seeing him. He gambles on half-times and things like that. He shows what his wins are, never shows what the losses are."Maybe that's why he's in the position he's in and he had to take this fight. I'm focused on the fight, not gambling."Mayweather - who retired from professional boxing in 2015 - raked in £266 million last year, but there are rumours his gambling addiction was the reason behind getting back into the ring.Those claims are unsubstantiated, of course, yet McGregor still used them to try and play mind games with his opponent.McGregor is aiming to become the first boxer to ever beat Mayweather, who boasts an impeccable record of 49-0 heading into the fight.And the Notorious is confident he can achieve the unthinkable, with his latest tweet about Mayweather one of his most emphatic and savage yet.McGregor plans to not only beat Mayweather, but destroy him, saying he can't wait to add the American's "skull" to his collection of previous fallen opponents.

MCGREGOR'S THREAT TO MAYWEATHER

Oh, and then there's the small matter of the diamond-encrusted belt the World Boxing Council has made especially for the fight.

As reported by TMZ Sport, the "Money Belt" contains 3,360 diamonds, 600 sapphires, 160 emeralds and approximately three pounds of 24 carat gold.

Both Mayweather and McGregor's names feature on the belt, too (see below).
