Brook and Khan will finally meet in Manchester on February 19, after a career’s worth of dancing around each other amid growing enmity.
The 35-year-old fighters had both harboured thoughts of retirement after this showdown, but any such plans could now be on hold.
Former IBF welterweight champion Brook insisted nothing will settle his feud with Khan, with the pair holding bitter resentment against each other.
Asked about a rematch clause, Brook replied: “I’ll be honest with you, I leave it all to my manager and my team. All I’m interested in is this fight.
“But I do know that there’s going to be a rematch in that. So if Amir Khan wants another beat down, he can have one!”
Asked if a defeat would make him consider his future in boxing, Sheffield fighter Brook continued: “I think some things I said before were taken out of context. A fighter who’s used to winning never has losing in their mind. I don’t think for a second about losing this fight.
“Every single day I’m growing in confidence, what my coach is saying, how I’m looking. Everyone in my camp, they can feel the buzz, the excitement, the body taking shape, my fitness is coming.
“The sharpness, the speed, the accuracy, it’s all coming. I’m not thinking about retirement, I’m thinking about Amir Khan on February 19. I’ve got my mojo back again and I’m really enjoying training; it’s brutal, but I’m loving it.”
Former WBA and IBF light-welterweight champ Khan has not fought since July 2019, while Brook lost to Terence Crawford in November 2020. Brook remains determined to prove himself the superior boxer, insisting he and Khan will never settle their differences.
Brook said: “It’s all animosity on my side and I think it is the same from him. 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.”
