Joshua produced a superb performance which enabled him to acquire a ninth-round stoppage win.
This win means that Joshua has started the second defence of his reign as world heavyweight champion in style.
“What can I say, this is the fight game, at the same time I’m not in competition with anyone apart from myself,’ Joshua said after the fight.
“I’m staying true to myself, learning every day, I get older, I get wiser, I learn that this boxing game is chess and not checkers.”
“I play a smart game and I make the right moves at the right time.”
“Round nine, I got the knockout and onto the next. It’s always good to see some great boxing,” he added.
Joshua dominated the fight throughout at Wembley’s SSE Arena and a stunning combination finally saw off the valiant efforts of his challenger.
Pulev had been down three times before at the fourth time of asking.
