10. Vasyl Lomachenko v Guillermo Rigondeaux
Arguably two of the greatest amateur boxers in history, having both won two gold medals each, these two have also picked up professional world titles in their respective weight classes and a fight between the two would be huge. The weight discrepancy between the two is not big enough to rule a fight out although Rigondeaux is not particular big at 122lbs, so a jump to featherweight could be an issue.
