Watch the weigh-in for the fight of the decade between Floyd Mayweather and Saul 'Canelo' Alvarez from 20:00 BST.
American Mayweather will put his unbeaten record on the line when he challenges the red-haired Mexican for the WBC and WBA super welterweight crowns at the MGM Grand Garden Arena and says he is ready for anything that Alvarez throws his way.
"If the game plan is to keep pressure, I can handle it," Mayweather, 36, said during the final news conference for what could end up being the richest fight of all time.
"If the game plan is to out-box me, nobody can out-box me. You have to be able to out-match me mentally, and I'm the strongest mental fighter in the sport of boxing. I've been here before so I know what it takes.
"He's 42-0, but he hasn't faced 42 Floyd Mayweathers because he'd be 0-42. I'm at the pinnacle. I'm the face of boxing," said the American, who prides himself on lightning hand speed and agile movement around the ring.
