The KO was vintage Joshua of old - the young boy who toured Glasgow, Sheffield, Liverpool and Newcastle cracking jaws when it wasn't such a serious game. Middle of the ring, one-two, jab and a right hand, bang. There was an arrogance and an aggression to Joshua's performance and his personality over the past three days that has been missing since he was shocked by Andy Ruiz Jr. The Ruiz Jr saga forced Joshua to be introspective and disciplined but, with the IBF, WBA and WBO belts back around his waist, he has not been in the mood all week to tolerate Pulev taking liberties.
