Oleksandr Usyk may be the reigning WBA, WBO, IBF and IBO heavyweight world champion, but to many, the Ukrainian is the underdog going into Saturday's long-awaited unification fight with Tyson Fury in Riyadh.
Size matters, it seems, with southpaw Usyk conceding 15 centimeters in height to the 206-cm Fury, 18 cm in reach, and close to 22 kilograms in weight.
And yet, he is not perturbed.
