Amir Khan and Kell Brook have both detailed their ill-feeling towards one another ahead of next month's fiercely anticipated bout in Manchester.
The two fighters are finally set to go toe-to-toe after a decade of rivalry, where Brook feels he has been shown 'disrespect' - while Khan says it's 'jealously' from his opponent.
All that adds up to what is set to be a thoroughly entertaining occasion and, ahead of their bout, their dislike of one another has been detailed.
"It's all animosity on my side and I think it is the same from him," Brook said. "There's no love lost, we don't like each other. This isn't just hype, this is as real as it comes.
"I don't like him, he doesn't like me. And I want to punch him hard. He's never given me any respect, or acknowledged me as a great fighter. I've always acknowledged him; I think he's done great in his career and I've never dissed him in that way.
"There's genuine dislike. I just don't like his face basically. He puts things out in the media and he puts it all on me. We both know it's never been me.
"All the years and spite between us, it means everything to both of us. There's definitely fireworks in this fight, make no mistake."
Khan countered with comments of his own, stating that Brook is merely jealous: "I'm doing this for the public, because it's what they want. If I don't take this fight, people will always say to me 'but you didn't fight Kell'.
"He says he's going to beat me and do this and that. I hope he tries to. But I just don't see him doing anything.
"The bad blood between us, I think it's pure jealousy from him. I'm going to destroy him. It's going to be a masterclass. I think he will need to retire after that; this will be his last fight."
