Oleksandr Usyk continues to make boxing look not only easy but something his heavyweight peers are still learning to do, writes Elliot Worsell.

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.
