The 45-year-old believes things could have turned out differently. There was a life-changing moment at Atlanta's 1996 Olympics when American boxing promoters approached him with a lucrative professional contract.

Todorov (right) turned them down -- a decision he regrets to this day -- being confident he would win gold and have a successful amateur career. He beat the 19-year-old Mayweather by one point in a controversial featherweight semifinal, leaving just Thailand's Somluck Kamsing (left) as an obstacle to Olympic glory.

But Todorov lost the final, claiming a silver medal while Mayweather signed up with the U.S. promoters, catapulting his career forward. He is now undefeated in 47 professional fights ahead of his long-awaited clash with Manny Pacquiao on May 2.

Mayweather vs. Pacquiao is expected to be the richest boxing match in history -- some tickets are on sale for nearly $130,000-- while Todorov, known simply as "the man who beat Mayweather," hopes to set up a small gym by the Black Sea.
