Former heavyweight champion Vladimir Klitschko (64-5, 54 KOs) referred to Muhammad Ali as the greatest boxer of all time.

He expressed this in a comment for DAZN Boxing.

"Who is the greatest boxer of all time? Muhammad Ali, without a doubt," Klitschko stated.

Recall that in early February, The Ring reported on Vladimir Klitschko's plans to return to boxing in 2025. The last time the Ukrainian fought was on April 27, 2017, when he lost to Anthony Joshua by technical knockout in a championship match.

Earlier, the BoxRec portal released a ranking of the best boxers in the history of Ukraine, where Vladimir Klitschko took the first place.
