The 39-year-old has regularly been mentioned in debates involving heavyweight greats from different eras, with many fans discussing how he would have fared against fighters such as Larry Holmes, Lennox Lewis, and Evander Holyfield.

Asked by Mail Sport Boxing to name the greatest fighter of all time, Usyk gave a short response.

“GOAT.”

Usyk was referring to Muhammad Ali, who remains one of the most recognizable figures in the history of the sport decades after his retirement.

Ali became a three-time world heavyweight champion and was involved in some of boxing’s most famous fights, including the “Rumble in the Jungle” victory over George Foreman and the “Thrilla in Manila” against Joe Frazier. Ali won an Olympic gold medal before beginning his professional heavyweight career.

He retired with 56 victories from 61 professional fights and is still widely regarded by many former champions and historians as the greatest heavyweight of all time.

Usyk is not the only modern heavyweight to place Ali at the top, with Mike Tyson also repeatedly calling him the greatest fighter the sport has produced.
