WLADMIR KLITSCHKO has warned Anthony Joshua not to repeat the mistake of allowing his focus from Saturday’s fight to be affected as it was by Tyson Fury.

Joshua defends his IBF title and hopes to win the WBA belt once held by Fury in what could be the definitive fight of his career against Klitschko at Wembley Stadium.

A crowd of 90,000, a post-war record for a fight in the UK, is to attend what is by some distance the biggest and most difficult match-up of his career, and Joshua perhaps betrayed some pressure when reacting as he did to his British rival.
