Bulgarian boxer Todorov, who beat Mayweather in the semifinals of the 1996 Olympics, believes that although it would be a difficult task, Pacquiao could defeat the American, who remains unbeaten on his 47 pro-fights.

Todorov suggested that Pacquiao should focus on keeping close in and mix up his style, adding that that is the only way for Pacquaio to outplay the American, the Daily Star reported. However, the Bulgarian wants Mayweather to win the mega-bout to continue to be the last man who defeated the American.
