Unbeaten Floyd Mayweather has had some strong words for his opponent Manny Pacquiao ahead of Saturday night's super-fight between the pair.

The contest at the MGM Grand Arena will be the richest fight in boxing history, and is expected to generate more than £300m for the pair, with the split going 60/40 in Mayweather's favour.

Mayweather, 38, is an 11-time, five-weight world champion, while the Filipino Pacquiao, 36, has won versions of the world title at a record eight different weights.

"I've never been defeated. I don't know what it means or feels like to lose. But once a boxer experiences that the doubt will always be in his mind," Mayweather said.

"Everything I do is calculated. Even keeping the world waiting for this fight, which would only have been worth about $60m if we'd done it five years ago.

"The way I fight my body hasn't taken too much hurt or damage.

"But Pacquiao is reckless. He's been in a lot of wars. I like to excite the fans, too, but if I'd been reckless I'd have been washed up by now. And when you risk getting knocked out as brutally as he was there will be repercussions later in life, after your career ends."
