Anthony Joshua seemed to give the winner's speech he'd prepared as he struggled to process his defeat by Oleksandr Usyk, says body language expert, before the loss finally hit him in his emotional press conference

Anthony Joshua was in a state of 'aggressive arousal' before delivering a bizarre post-fight rant after losing his heavyweight clash against Oleksandr Usyk in Saudi Arabia on Saturday night, according to a body language expert.

British star Joshua lost the third fight of his professional career in Jeddah - and his second in succession against the Ukrainian - which put him in a state of 'cognitive confusion'.

That is believed to have affected his mental state after the bout, leading to his foul-mouthed rant, throwing the belts out of the ring, which has divided the boxing fraternity.
