World featherweight champion Nicholas Walters insists he does not recall his amateur defeat to Saturday night's opponent Miguel Marriaga.
Walters (25-0-0) will put his WBA (super) featherweight champion status and his unbeaten professional record on the line at Madison Square Garden, where he faces the dangerous and undefeated Colombian.
But when asked of the defeat to Marriaga before the pair turned pro, the Jamaican said: "Marriaga may have beaten me in the amateurs but I do not remember it. Besides, those fights are four rounds. On Saturday we will be fighting 12 rounds.
"He may be bringing his ‘A Game’ but I am bringing my ‘A-Plus Game’. I have trained for a knockout victory. I am going to destroy him.
"I am overwhelmed to be fighting at Madison Square Garden, the Mecca of boxing, because so many of boxing’s great champions have fought here. It is hallowed ground. It is my honour and I want to give my best performance there.
"To be great – to be known as the best – you have to beat the best and I am ready to take on all champions in my division and beyond."
Marriaga, who has stopped 18 of his 20 opponents to date, is suspicious of Walters' claim and said: "Of course Walters doesn’t remember me beating him for a spot on the Olympic team – because he lost! He’s not going to remember this Saturday for the same reason.
"I have the strength and the intelligence to beat him and I will use my strength and intelligence. After I beat Walters again on Saturday I look forward to unifying the titles in my next fight."
The match-up will no doubt be of great interest to Welsh hero Lee Selby, who became IBF champion at the same weight division by beating Evgeny Gradovich with an eighth-round stoppage at the O2 Arena last month.
