The last training session ahead of Anthony Joshua’s big fight against Dominic Breazeale at the O2 saw me shooting the big man in action on behalf of his new sponsor Lucozade.
People talk about his big right, not to sure I’d want to get in the way of the left either. AJ won the fight with a 7th round KO.
