Floyd Mayweather deems a lesser-known fighter to be the toughest opponent of his career.
But 'Money' believes Emanuel Augustus - called Emanuel Burton at the time - gave him the most difficulty inside the squared circle and even outdid him when it came to showboating antics.
Augustus, nicknamed ' the Drunken Master' thanks his bizarre punch sequences and unique puppet-like approach, retired with a record 38-34-6 record.
Coming into the bout in October 2000 in Detroit, he had 22 wins and 16 defeats in his professional career but he gave Mayweather, who had been super featherweight world champion for two years at the time, some serious trouble.
He was eventually pulled out of the fight in the ninth round yet earned the respect of Mayweather, who had his nose bloodied by him in the fifth after some combinations.
"If I was rating certain fighters out of every guy that I fought, I'm going to rate Emanuel Augustus first compared to all the guys that I've faced," Mayweather stated.
