Oleksandr Usyk has become boxing's undisputed heavyweight champion for a second time after beating Britain's Daniel Dubois at a packed Wembley Stadium.

Ukraine's boxer Oleksandr Usyk speaks Thursday as he meets the Ukrainian war veterans at a hotel in Battersea Park in London.

Usyk and Ali’s physical attributes are also very comparable. At his peak, Ali stood at 6ft 3in tall, had a 78in reach and weighed around 220lbs. Usyk is the same height and has an identical reach. He has also resisted the temptation to bulk up too much since moving to heavyweight.

Tyson Fury found himself puzzled by Oleksandr Usyk's cryptic "don't be afraid" comment as the pair prepared for their eagerly awaited rematch in December. Usyk, who made boxing history by becoming the first fighter to defeat Fury professionally with a split-decision victory last May, beat him once again just before Christmas.
