For an up and coming star such as Chris Eubank Jr, the chance to train with Floyd Mayweather was an opportunity impossible to turn down.
Mayweather came out of retirement to face UFC star Conor McGregor last month and secured the 50th victory of his career with a stoppage in the 10th round.
Although the controversial American isn't exactly the most well-liked sporting figure in the world, there is little doubt he will be remembered as one of the all-time greats.
However, despite emerging victorious from the huge Las Vegas bout, the nature of Mayweather's preparation in the days leading up to the fight might surprise you.
Eubank Jr was invited to help equip the 40-year-old for his comeback fight and has revealed seeing him at pool parties and strip clubs was not what he was expecting.
"Two weeks before the fight I watched him walk out of the strip club at five in the morning, it’s surreal," Eubank told the Daily Mail.
"It’s like: 'Jesus'. Then the next week he’s at a pool party. He’s not drinking and he’s got his section up at the top and he’s just chilling and stuff but it’s like: "You’re at a pool party and you’re about to fight in a week and half’s time, who does that?” Well, Floyd does that.
"Everybody is different and the thing with Floyd is, in a good and a bad way – well it’s good for him obviously because it works for him."
There had been claims from elsewhere in Mayweather's camp to suggest the former five-weight world champion had not taken the McGregor fight entirely seriously and Eubank's comments appear to prove it.
The fact he still managed to beat his Irish opponent so convincingly as well is a testament to the natural ability Mayweather still possesses.
Of course, that probably isn't the best example to set for aspiring youngsters, though, but Eubank insists Mayweather's unorthodox approach will not affect how he prepares for fights.
The 28-year-old added: "You have kids who are looking at (Mayweather's lifestyle) and thinking 'Oh I can do that, I can go to the club and party and do whatever I want and then fight'. And you just can’t. You just can’t.
"I’m a grown man, I’m 28 years old now. I’ve been doing this for so many years I’ve got my routine and I’m very strong mentally.
"If you’re not strong mentally, if you’re young, you can get swept up, you can get sidetracked, you can see a lifestyle and that’s what you want and you start putting boxing second."
Eubank Jr, the IBO super-middleweight champion, returns to the ring on October 7 against Avni Yildirim in the World Boxing Super Series.
