Two of the most respected fighters in the history of Mexico, Juan Manuel Marquez and Erik Morales, are shaking their heads at the upcoming fight between Saul "Canelo" Alvarez and "Sugar" Shane Mosley. Canelo will make the fourth defense of his title against Mosley, a former three division champion, on May 5th at the MGM Grand in Las Vegas.

Marquez and Morales believe Mosley is a finished product and even his name value is not what it used to be because of the recent performances against Manny Pacquiao, Floyd Mayweather Jr. and Sergio Mora. They feel Mosley is looking for a final financial slice before walking away from the sport.

"Against Pacquiao, Mosley was afraid. He was afraid, even though he said over and over again that he wanted to win and convince everyone [that he was still the best]. I think Mosley is in the last stage of his career and he wants to retire in a good financial state. I see no point in Canelo facing him, as Mosley's name lost its taste a long time ago and he does not represent a major challenge for Alvarez," said Marquez, who expects Canelo to win by knockout.

For his part, Morales says Canelo has to take fights where people remember that he's a good champion and beating Mosley will not do much for him.

"When you become world champion, most often people will criticize the way you do it - but once you get there, great fighters want to make history. Mosley is a fighter who was once great, but things have not gone well for him in his last few fights. He has been criticized a lot and has a history, but his career is over and that has been very evident, because in his last few fights he was beaten very easily," Morales said.
