British lightweight contender Luke Campbell believes his legacy will be secured, in beating Vasyl Lomachenko in their upcoming clash.
Campbell and Lomachenko will collide for the WBC, WBO, WBA lightweight titles on August 31 in the UK.
The fight, according to both promoters, is already finalized. The bout is expected to be announced in the coming days.
Both boxers captured Olympic gold, in their respective divisions, in the 2012 Games in London.
Lomachenko is regarded as one the best pound-for-pound fighters in the sport.
"It will be the toughest challenge of my career but I'm up for it," Campbell told BBC Sport. "He's a class fighter. He can do everything. You don't get ranked like he is for nothing do you? But how do I get in that list? I'll tell you how, 31 August.
"I believe I am the best and everybody will see in this fight. This is a mega fight here in the UK. We have not had a fight like this in a long time. Two guys, both at the top of their game, fighting off."
Campbell was in line to fight for the vacant WBC title - and he was surprised when the sanctioning body ordered him to face Lomachenko, who already was a world champion with two rival organizations.
"He wasn't ranked anywhere in the WBC," Campbell added. "Then his name started getting mentioned in who I could face for the title. They put him in from nowhere.
"It's definitely a harder path to a world title but I am not bitter or mad. I want to prove I am the best. To do that you have to fight the best. Everything happens for a reason. He was either getting beat if we fought in a couple of fights time or now in this fight, so it doesn't make a difference to me. I have never had it easy have I? I fought Linares for a world title - a Linares at his prime, in the US, in his back garden. I relish these opportunities.
"There are kids who have won titles a lot easier but at the end of the day my story will be better. At the end of the day I am very grateful to be where I am. There are a lot of guys out there who aren't as fortunate as I have been in boxing. Lomachenko has a lot of tricks. He's a trickster. I am not a trickster. What I'll do is give it 100%, go in there, do what I do very well and hit you hard. I don't know if you have got the vibe but I am up for it, very focused. If you are not focused fighting someone like this guy, you never will be."
