Floyd Mayweather Jr. and Canelo Alvarez are two exceptional prizefighters who have always brought a certain anticipation amongst boxing fans.

The arrangement would help establish him as a megastar, well on his way to cementing his name as a boxing legend.🔫 Floyd Mayweather savaging Canelo Alvarez on Instagram after he signed five-year deal with DAZN worth a minimum of $365million. pic.twitter.com/tGhgOcSODo— Michael Benson (@MichaelBensonn) October 18, 2018On September 14th, 2013, Alvarez would face his greatest test in the ring yet against multiple-division world champion Floyd Mayweather Jr. In what was a clinical display of skill and finesse, Mayweather took Canelo to the cleaners, effectively leaving him to re-think his knowledge of the sweet science.Has Floyd Mayweather retained his wealth over time?Aug26.20173 years ago today,Conor McGregor & Floyd Mayweather competed in one of the most lucrative fights in combat sports history. pic.twitter.com/fuYJTio9QK— MMA History Today (@MMAHistoryToday) August 26, 2020Conor McGregor's super-fight against Floyd Mayweather may have been regarded as a mismatch, but Floyd seemed clear about his intentions from the very beginning.
