I'm going to rebuild Miller's face – Joshua
World heavyweight champion Anthony Joshua studied Jarrell Miller more than any other boxer to avoid a "banana peel" when the duo will meet at Madison Square Garden on June 1st.
The 29-year-old Briton said live on BBC Radio 5 that he "could not afford to make any mistakes" when defending his IBF, WBA and WBO titles against the American.
"He is the first fighter where I know what he says, acts and feels," said Joshua.
"I do not want to sneak up against him."
When the BBC informed Miller of the extra attention Joshua gave him, he said, "It does not surprise me. [WBC champion] Deontay Wilder did his best not to mention my name because the media are starting to ask me questions.
"I just got my file and did what I could. But since I was too tired to wait, I started attending press conferences and talking to junk shops to get their attention.
"If it was left to them or [promoter] Eddie Hearn, the fight may not have happened any time sooner. Being a media force and telling them how I feel … I'm real and funny – people gravitate towards that. "
Miller will almost certainly be the heavier opponent Joshua has met as a professional, weighing 22 pounds for the last time.
Earlier on Monday, the two men clashed at the press conference in London, saying Joshua would "rebuild" Miller's face in New York during what will be the British's first fight in the United States.
Joshua reacted to the 30-year-old's suggestion that he had enjoyed a privileged path to success.
"I was banished from the area in which I was growing because I had too many problems," added Joshua.
"The state of my hands – it's not boxing, but streetfighting – I've completely changed my lifestyle."
"All that boy's spirit and the rubbish he's talking about, I'm going to take it off him." Look at his face – I'm going to rebuild his face and body on June 1 and I'm looking forward to this challenge.
"I'm going to be a surgeon because I'm going to give him a makeover."
Miller has 19 straight wins after a draw in 2013
