Anthony Joshua is determined to heed the words of Lennox Lewis and put the past behind him when he meets old foe Dillian Whyte at London's O2 Arena on Saturday.
The pair will face off for the British and Commonwealth heavyweight titles this weekend in a bid to settle the bad blood that has existed between them since Whyte's 2009 victory in their meeting as amateurs.
Comments from Joshua on Whyte's 2012 ban for a failed drugs test led to the latter branding his opponent a "snake", but the 26-year-old has revealed how the advice of former undisputed world heavyweight champion Lewis is helping him ignore any pre-fight distractions.
Joshua (14-0-0, 14KOs) said: "When I turned pro, Lennox Lewis said to me: 'forget what you did as an amateur, you are a pro now'. I take that attitude into this fight, it's come from a true great so I'll take that mentality on-board.
"With or without the amateur win we'd be here. It has given him belief and something that he can say he has over me, and mentally he's living off that."
Joshua has won all 14 of his professional fights by knockout and is yet to be taken beyond the third round. However, the 2012 Olympic gold-medalist said he was expecting a tougher challenge against Whyte (16-0-0, 13KOs) and admitted the bout could even extend into the fourth round and beyond.
"He's trying to get me to take my eye off the ball and abandon my game plan, just go in and swing wildly," Joshua said. "I know that and it's not going to affect me. He's a good fighter, this could be the fight that I am taken past two or three rounds, which is what I've been doing so far, so I have trained for a long fight."
Whyte has sought to ramp up the trash-talking ahead of this weekend's showdown, labelling Joshua a "fraud" and likening him to former British heavyweight Audley Harrison, but Joshua insisted he would do his talking in the ring.
"There's nothing fake about providing for your family, earning a righteous living, doing something that you are passionate about," he said. "I can't control his mouth and what he thinks of me.
"The closer the fight has come, the quieter he has become, maybe it's dawned on him what is going to happen. I am locked in the zone when I train so nothing can distract me or stop me."
