Oleksandr Usyk has mocked Anthony Joshua's training regime and offered to help the British heavyweight boxer 'establish a better team' once he retires from the sport.
Joshua lost his WBA, WBO, IBF and IBO titles to the Ukrainian southpaw at the Tottenham Hotspur stadium in September - having been comprehensively outclassed over 12 rounds.
Long-term coach Rob McCracken - who oversaw Joshua's ascent to an Olympic gold medal and the world titles above - was the major casualty of AJ's loss, given the fact the 32-year-old decided to part ways with him in October.
