Floyd Mayweather Jr is boxing's best pound-for-pound fighter and also the highest paid athlete in the world, but he is also known for being a braggart with an outrageously ostentatious lifestyle. The man that Mayweather's 'Money Team' see away from the public eye, however, is more than just boxing's bling king.
From within Mayweather's training camp, former British light-welterweight champion Ashley Theophane describes someone at odds with his public persona; instead of self-absorption and obsession with wealth, he finds extreme hard-work and inspiration.
"Floyd's worth so much money but he is still working so hard and it proves that what you put in, you get out," 34-year-old Londoner Thephane said. "I've never seen a more hard-working champion than Floyd - and he's also a nice guy. He's always there ready to give some advice, always got time for a chat. The other day he finished working out and started asking me about my amateur career."
Theophane is training alongside Mayweather, who is also his promoter, in Las Vegas ahead of his next fight on April 30. In the two years that he has been working with the American, he has never seen Mayweather, 38, as focused as he is on his long-awaited showdown with Manny Pacquiao at the MGM Grand in Las Vegas on May 2.
Mayweather-Pacquiao will generate revenue upwards of $300 million (£203m) and the world welterweight title unification clash is the biggest fight in decades. Mayweather could earn a staggering $180m (£122m) from the blockbuster but Theophane, who has probably not earned $1m (£677,000) in his entire career, says the vast amount of lottery-numbers wealth banked and available has had no impact on the American's hunger or work-rate in the gym.
"I've been looking forward to this camp because I know that when Floyd is in the gym there's going to be buzz about the place. When I watch him work it rubs off on you," Theophane said. "It's a privilege because I'm getting to see Floyd work up close and it is inspiring me to be the best that I can be. Floyd trains for two or three hours, has a shower, and then goes running for however many miles. It's crazy what he does. I've never seen anyone work so hard in training.
"I usually go running with Floyd twice a week. He's always focused but it seems he wants it more in this camp because it's a fight that has been spoken about for so many years. He's a funny guy too and likes to joke around, but you don't always see that when the cameras are around.
"Being part of this camp is something I will be able to look back on and talk about in years to come, especially as I'm the only British guy in with Mayweather."
So, he's hard-working and inspirational, but does Mayweather look like he is ready to reach his peak next month? "He's already dropped three of his sparring partners," Theophane recounts before addressing the speculation that they undefeated champion was floored by former world champion Zab Judah in the training ring. "Zab definitely did not put Floyd down," he says. "Floyd got the better of the spar with Zab."
He's also going to get the better better of Pacquiao, Theophane insists, not least because Mayweather possesses a type of power that prompts his opponents to attack prematurely - a trait that has cost Pacquiao in the past.
"If Floyd was to catch him with one of those punches he could stop him," the Londoner adds. "I think the first four rounds will be back and forth and then Floyd will take over, so I think it could be a wide points win or Floyd to stop him in the middle to late rounds."
Away from the super-fight training, Theophane has been told by Mayweather that he is on course to compete for a world title before the year is through, if he keeps on winning. The identity of his next opponenton that journey, however, has not yet been confirmed.
"I'm going to be fighting at Palms Casino and Resort in Vegas on April 30, which will be great because there will be a lot of press in town that week for the big fight between Floyd and Manny," Theophane says. "Hopefully it will mean my fight will get a bit more exposure because of it.
"I'm just waiting on an opponent now. There's a former world champion in the mix and someone who has fought for the world title.
"Floyd told me last week while we were running that he's going to get me a world title shot and it will come this year. A lot of the top guys at light-welterweight have moved up a division and that hopefully will create openings.
"There's Adrien Broner at light-welterweight, and I think Danny Garcia will move up a division after his fight with Lamont Peterson. Me against Peterson would be a great fight, and I would choose him if I could to fight for the world title."
In the short term, Theophane will settle for a win on the eve of his training partner's big night - and perhaps an invitation to the main event.
"I'm hoping to get a ticket for the big fight," Theophane admits. "Maybe if I put in a good performance in my next fight Floyd will get me a ticket as a reward!"
