Anthony Joshua's 'will and desire' to be a world heavyweight champion has been called into question by the father of his main rival.
The Brit lost his titles in September at Tottenham Hotspur stadium when he lost a unanimous points decision to Oleksandr Usyk.
The defeat deralied his attempts to secure a unification bout with Tyson Fury - who held up his part of the bargain by beating Deontay Wilder in the States earlier this month.
And Fury's father John has suggested AJ will struggle to return to his former heights after losing his belts for a second time, insisting he does not possess the same spirit as his son - or his most recent opponent.
