Manny Pacquiao is preparing for his 70th professional fight on Saturday night as he defends his WBA regular welterweight championship against American Adrien Broner.

The Filipino boasts a healthy 60 wins, two draws and 7 losses in his professional career, which began way back in January 1995.

Arguably the first ‘big fight’ of 2019, Broner was once described as the heir to Floyd Mayweather’s throne and the American has an impressive 33 wins from his 37 professional bouts.

Pacquiao will return to the MGM Grand in Las Vegas for the clash with Broner, with former rival Mayweather recently confirming his appearance at ringside for the highly anticipated clash, amid rumours of a sensational rematch between Pacquiao and Mayweather.

Pacquiao, who turned 40 last month, and Mayweather, 41, are undeniably two of the best pound-for-pound boxers of all time, so here at Read Boxing, we’ve decided to take a look at the top 20 pound-for-pound boxers over the past 20 years.
