Former four division world champion Erik Morales remembers when was a big underdog against Manny Pacquiao in 2005. Morales was coming off a loss to Marco Antonio Barrera, but he found the magic to hand Pacquiao a twelve round decision loss. Morales would go on to lose his next four fights and Pacquiao remained without another blemish until June 2012.

Morales now reflects on the big match that involves his countryman, 22-year-old WBC/WBA junior middleweight champion Saul "Canelo" Alvarez (42-0-1, 30KOs), who faces Floyd Mayweather Jr. (44-0, 26KOs) on September 14th at the MGM Grand in Las Vegas.

He notes that Mayweather has faced issues in both of his prior junior middleweight fights, against Oscar De La Hoya and Miguel Cotto. Both of those opponents were past their best. Canelo is younger, stronger and bigger than De La Hoya and Cotto.

"It's an interesting fight, where no doubt the battle of youth against experience will be a defining factor. The fight is like a mystery, it brings out the curiosity in you, the desire to see that fight. Floyd is a fighter who most of the time has selected opponents where he was in a somewhat comfortable position. Canelo has also been in with opponents where he was somewhat comfortable. The important part is where Floyd has the experience and Saul is young, strong - and we expect to see a great fight," Morales said.

"Floyd has never faced such a strong young man, a fighter who is willing to offer everything of himself to win and has nothing to lose. You have to respect the hierarchy of Mayweather. It is going to be interesting because Mayweather always handles himself well the ring, keeps a good distance, and he does not like to be hit. He throws many slapping punches, simply with speed and not with any real technique, and [those punches] are a great nuisance."

"Canelo is young, strong, fast, but he does not have the continued pace to put together combinations. He always studies [his opponent], and looks for openings to land his shots. This [fight] will be a good measuring stick to see where his boxing [abilities] are at."
