The fight has finally arrived after years of back-and-forth words.
Former world champions Amir Khan and Kell Brook will finally collide this coming Saturday night at the Manchester Arena - in a British grudge match that sold out in record time.
For this fight, Khan traveled across the ocean to work with veteran trainer Brian 'Bomac' McIntyre, who is best known for his work with WBO welterweight champion Terence Crawford.
Crawford, who holds stoppage wins over both Khan and Brook, assisted the Bolton man in camp.
"The altitude in Omaha and Colorado Springs was very, very difficult. We've just got back, so still got the benefits of doing it. I've done a 12-round spar and an eight-round spar, finished off with the eight-round spar and it felt so easy! The oxygen, it just felt like there was too much of it," Khan told Sky Sports.
"It's amazing to know that I've got the fitness on my side. I've got the health, I've got the strength and I've got the team around me as well...They've got me in good shape. We're going to go into this fight and win this fight. We've been focused in Omaha, up in the mountains in Colorado Springs, focused on our training. We don't care what Kell and his team are doing."
Most insiders are predicting an early night - with a knockout ending by either man.
Khan is expecting to close the door on their longtime rivalry by stopping Brook.
"His confidence is brittle, definitely," Khan said. "And I can see right through him. You can see how he reacts when I talk to him. You could see he really dislikes me and hates me, which is normal. We're going to be fighting each other come Saturday.
"But I just think it's getting to him a bit too much where it could definitely throw his game-plan out the window, where he's going to go into a fight, guns blazing, make mistakes and get caught himself.
"I'm staying calm. I find it quite funny when I speak to him and I can see the anger in him. I just kind of mess around with him really, to be honest. That's what it's come down to. I pick on things, and I know it's going to get under his skin.
"But come fight night, we have a game-plan. I'm sure he has a game-plan. He's going to be ready, he's going to be prepared for the fight, like me. And we're going to give the Manchester fans a massive fight."
