Anthony Joshua has predicted he will knock Jarrell Miller out in the fourth round when the fighters meet at Madison Square Garden on June 1.The pair squared off at the famous New York venue and in an interview with DAZN, was asked for a prediction and admitted he was previously targeting a seventh-round finish but now plans on knocking 'Big Baby' out in four.World number one Joshua, 29, is undefeated in his 22 professional fights and has won by knockout in 21 of those bouts; his other victory coming via a unanimous points decision against New Zealand's Joseph Parker in 2018.Miller is a born and bred New Yorker and will have the home advantage when Joshua fights in the States for the first time.In a fiery press conference on Tuesday Miller pushed AJ as they squared off, and Joshua thinks he has only made it worse for himself.“I can beat him easy but now like, I think I’ll nearly murder him so I think he’s just making it worse for himself,” he told DAZN."I (previously) said round seven but (now) I think round four, round five."The Watford-born boxer said that it would be like stepping into the lion's den and insists he is fresh and looking to enjoy himself.

“I’ve learnt from a lot of my fights I’ve been dropped, I’ve got back up, I’ve been tired, I’ve fought champions, I’ve beaten them all.”

The Olympic champion added: “Jarrell Miller is just stepping into the lion’s den with a roaring lion.”

The pair fight on June 1 as the Big Baby attempts to take all of Joshua’s belts.

Joshua will be looking to use this fight as a time filler before he can fight Deontay Wilder in order to become the undisputed heavyweight champion, the first to do so since Lennox Lewis in 2000.

Wilder still faces a potential rematch with fellow British boxer Tyson Fury following their enthralling draw in Las Vegas in December last year but Joshua has continuously expressed his desire to fight the American.
