Shane Mosley believes it was his destiny to meet Floyd Mayweather Jnr in the ring despite years of being avoided by the 'Money' man.
Mayweather appeared certain to fight Manny Pacquiao this year and although that megafight never came to pass, Mosley believes the fight on Saturday week is the one fans want to see.
Mosley has 'called out' his opponent for several years, having fought the best throughout his distinguished career.
The 38-year-old is enjoying a glorious twilight after regaining the WBA welterweight title against Antonio Margarito more than 12 months ago.
And one final victory against the undefeated Mayweather would cement 'Sugar' Shane's place in boxing's Hall of Fame.
"It's a fight the world wants to see," he said. "I have to be honest, I thought they were going to be able to avoid me.
"I thought they would be able to fight each other and retire. But this is the fight that had to happen. This is a fight of destiny."
Mosley, having fought at welterweight or above since stepping up from lightweight in 1999, believes he not only has a since advantage over Mayweather, but will also match him for speed.
"As a welterweight, he hasn't fought any of the top welterweights," he said. "I'll be the first one. I think I'm as fast as any fighter out there.
"I've always been one of the fastest. I've never been in the ring with Floyd, so I'm just going to do what I do best, be Sugar Shane Mosley.
"He has good hand speed, but I think my hand speed is good too.
"This is a competitive sport. This is our legacy. It's a challenge that I'm ready to take. I'm ready to go into the history books as the guy who beat Floyd Mayweather, the guy who beat everybody out there, the last man standing."
