Shane Mosley believes he will succeed where 40 others have failed when he takes on the undefeated Floyd Mayweather Jr in their welterweight bout on May 1 in Las Vegas. Sugar Shane plans to become the first fighter to beat Money Mayweather and insists entering the ring void of emotion is the key to victory.

Mosley, 46-5 (39 KOs), maintains he won’t allow Mayweather’s trash talking get to him and will be focussed come fight night.

"I think a lot of people who have fought Floyd have let his talking get to them and they go into the fight angry,” said Mosley, who has never been knocked out. “They are fighting with their emotions when they are in the ring. I'm not going to do that. I know how I want to fight Floyd and I know what I want to happen, so I am going to do what I have to do to win.

"A victory over Floyd Mayweather would definitely rank in my top victories. It would let people know that once again they overlooked Sugar Shane Mosley and that was a mistake.

"Floyd is a great fighter and there are a lot of different things he can bring to the ring. But there are a lot of things I bring as well. On May 1 we are going to find out who the real chess player is.”

Mayweather has a perfect record of 40-0 (25 KOs) but Mosley believes that goes for nothing and is ready to become the first person to beat the 33-year-old.

"I think there is too big a deal being made about the fact that Floyd is undefeated. Before my first loss I was 38-0 with 35 KOs. That's a hell of a record, but that didn't mean I couldn't be beat and it doesn't mean Floyd can't either.

"It might be harder to fight someone who hasn't lost before because they really don't want to lose, but when you are fighting anyone on this level it's going to be tough. No one wants to lose, so I don't think that is going to be an advantage for Mayweather.

"There is a clause in the contract that says Floyd gets a rematch if I beat him, but I would give him the rematch anyway, because it would be great to beat him twice.”

The 39-year-old Mosley knows he is in for a tough fight but is confident in his own ability against such a formidable opponent.

"Floyd Mayweather is good, but I'm going to be fast. He's never had to deal with speed and skill like Sugar Shane Mosley's before. I'm a full-time fighter; it's a lifestyle for me. I love to do what I do.

He added: "I'm going to do everything on May 1. I'm going to attack. I'm going to box a little. I'm going to do it all.

"The theme of this fight is 'Who R U Picking?' Well people should be picking me because I have proven that I can knock people out in any round. I'm experienced and I have the speed, power and agility to win this fight."
