Trainer Robert Garcia knows that defeating Floyd Mayweather Jr. is a gigantic task, but the world-renowned trainer is mapping out a fight plan he thinks will work against the reigning pound-for-pound king.

In an interview with BoxingScene, Garcia said that his fighter, Marcos Maidana, will be very aggressive in his upcoming showdown against Mayweather on May 3 at the MGM Grand in Las Vegas.

Garcia said that Mayweather's defense is tough to break, but he revealed that Maidana is planning to throw at least 100 punches each round to keep the undefeated champion guessing.

"Mayweather is very defensive and doesn't throw a lot of punches. With Maidana, I will prepare him to throw 100 punches per round. Winning won't be easy, but nothing is impossible," Garcia stressed.

Garcia, the 2012 Trainer of the Year, also reiterated that Maidana is not afraid of Mayweather. The 37-year-old Grand Rapids native is far from unbeatable at this point of his career, said Garcia.

Garcia pointed out that boxing greats like Muhammad Ali and Ray Leonard were also considered unbeatable during their primes, but both legends still absorbed defeats.

With that in mind, Garcia insisted that Maidana will be 100 percent ready to face Mayweather, adding that the 30-year-old Argentinian is also ready to fight dirty and give Mayweather a dose of his own medicine.

"The best have lost," Garcia stressed. "[Ray] Leonard lost, [Muhammad] Ali lost. Everyone who goes against Mayweather is afraid. And Maidana will be physically and mentally ready for twelve intense rounds. He's going to fight dirty, tough and strong."

Maidana, who is coming off a dominating win over Adrien Broner, also expressed confidence that he can handle Mayweather in their upcoming showdown.

Maidana vowed to seize the big opportunity given to him, confidently saying that he can score a knockout victory over his heavily-favored opponent.

"I wanted to earn this fight to remain in the history of Argentine boxing. That's why I wanted this fight very much. It is a very big opportunity for me. I believe that with the type of punches that I throw, I can knock him out," Maidana said, Boxing Scene reported.
