Former heavyweight champion Vladimir Klitschko (64-5, 54 KOs) has declared Muhammad Ali the greatest boxer in history.

He made this statement in a recent interview with DAZN Boxing.

"Undoubtedly, the greatest boxer of all time is Muhammad Ali," Klitschko stated.

It’s worth noting that earlier this February, The Ring reported on Klitschko’s intention to make a comeback to boxing in 2025. His last fight was on April 27, 2017, where he lost to Anthony Joshua by technical knockout in a championship bout.

Additionally, BoxRec recently released a ranking of the best boxers in Ukrainian history, placing Vladimir Klitschko at the top.
