Many AJ fans, include Tony Bellew, have warned Joshua not to underestimate the speed and tactical ability of Usyk.

Joshua will want to avoid a repeat of his shock defeat against Andy Ruiz, in 2019. Despite giving up a huge 38lb weight difference, Usyk showed his pedigree as a fast and nimble fighter against Chisora.

Coming from the same training camp as Vasyl Lomachenko, Uysk has incredible stamina, and is able to attack from tricky angles which can disrupt even the most tactically organized boxer.
