Oleksandr Usyk may not be Tyson Fury, but make no mistake - Anthony Joshua is in a real fight this weekend.
The slick southpaw, a former Olympic gold medallist and undisputed cruiserweight champion, is undefeated as a professional and cannot be taken lightly.
Joshua is the favourite to retain his world heavyweight titles in Tottenham, but there is a perceptible element of trepidation around this fight that isn't usually there when AJ performs.

Even his own promoter Eddie Hearn admitted he is going to be in for a long night and at times may be watching ringside through his fingers.
