Marcos "El Chino" Maidana feels confident about his chances against Floyd Mayweather Jr. in their upcoming showdown on May 3 at the MGM Grand in Las Vegas.

In an interview with BoxingScene on Tuesday, Maidana admitted that beating Mayweather will be a gargantuan task, but he believes he has the power to hurt the reigning pound-for-pound king, and possibly score a knockout.

"We all know he's a great champion but I'm preparing well and every time I fight a good opponent and I catch him with a good shot I hurt him and I could knock him out. With Mayweather, I expect to catch him with a good shot and I feel I'm going to hurt him too," Maidana said.

Maidana, who will put his WBA welterweight title on the line, will be a heavy underdog heading into Fight Night, but the 30-year-old Argentinian is unfazed, saying that he is used to being an underdog.

"Every time I come into a fight with a good opponent, I'm always the underdog, I'm never the favorite. But that doesn't matter because I like to give surprises," Maidana said.

Maidana is coming off an upset victory over then-unbeaten Adrien Broner in their title showdown in December last year. He was also a heavy underdog before the fight, but he managed to defy the odds, knocking Broner down in rounds two and eight en route to a unanimous decision win.

Boxing analysts believe that Mayweather and Broner have similar fighting styles, but Maidana pointed out that Mayweather is way better than Broner because of his speed and experience.

"I think Mayweather is much faster, walks the ring more and has more experience. They have a similar style but it's not the same thing," Maidana said.

Maidana also insisted that Mayweather made the right decision of fighting him instead of British boxing icon Amir Khan, saying that a Mayweather vs Khan showdown would have been a boring fight.

"I think Khan vs. Mayweather would be a very boring fight," Maidana said. "They are both boxers and neither of them are going to attack, so that's why I think it would be boring."
