Former three division world champion "Sugar" Shane Mosley is probably one of the best experts to give an opinion on the May 5th mega-bout between Miguel Cotto and Floyd Mayweather Jr. Mosley fought, and lost, to both boxers. Mosley lost a twelve round unanimous decision to Cotto in November 2007 and nearly three years later, in May 2010, he lost a twelve round unanimous decision to Mayweather.

Next month at the MGM Grand in Las Vegas, Mayweather (42-0, 26KOs) challenges Cotto (37-2, 30KOs) for the WBA's 154-pound title. Mosley faces WBC junior middleweight champion Saul "Canelo" Alvarez in the co-feature.

"It will be a very interesting and difficult fight for both of them. Cotto has power in his punches. He is a very strong boxer who knows how to use his punches, but his intensity seems to go down as the fight progresses. Mayweather is a fast boxer with great skills in the ring and he can be adjust in the middle of the fight," Mosley said.

"The first four or five rounds of the fight will be crucial and [those rounds] will define the rest [of the fight]. If Floyd does not take him seriously, Miguel could emerge victorious."
