No defeat has stung for Anthony Joshua like the loss by Oleksandr Usyk. And it showed in his erratic behaviour and rambling rant in the ring and a press conference during which he fought back tears.
When he was beaten by the Ukrainian at the Tottenham Hotspur Stadium last September, he could rationalise it, he could see how he could do better. Likewise, when he lost against Andy Ruiz Jr in New York in 2019, he was caught cold by a punch. It is boxing, it happens.
