Carl Froch and George Groves came face-to-face for the first time since their thrilling fight last year.
The pair took centre stage at a press conference to promote their eagerly-awaited rematch at Wembley Stadium on May 31, live on Sky Sports Box Office.
Sixty thousand tickets that went on sale on Monday sold out within an hour. Promoters are now seeking permission to sell extra tickets.
Froch retained his WBA and IBF super-middleweight titles with a controversial stoppage in November but Groves is determined to set the record straight.
"Well this is it, everything for a reason," said Groves. "We got the rematch, we got it in Wembley."
"Carl Froch has been mandated. He now has to fight a fight he doesn't want to take, a fight that he knows he can't possibly win.
"It was a stone-wall robbery last time. Everyone knows it, the IBF know it, that's why they have instated me as mandatory with an immediate rematch that is now taking place.
"It brings me great joy that this is happening because otherwise this is not a fight that was going to take place.
"This is not a fight that he can take, it's a fight that he can't get up for, it's a fight that he didn't want, and he is going to struggle for motivation. He wanted to go to Vegas, he wanted to fight (Julio Cesar) Chavez (Jr), he didn't want to take this fight, but he's been forced to take this fight.
"I think that's round one to me, round two is because we are sitting here in Wembley, my home city. Carl has now got to travel down to London now, he's got to come all the way here to my home town and fight in front of my fans.
"This will be a national event and people will travel for it. This is my home crowd and maybe that's fate, I don't know, maybe everything for a reason.
"This is perfection for me now Carl, everything I do in this will be for a reason. There is not one thing that will be chance.
"It's not going to be whether I choose to hit you in the head or the body; it's whether I choose to hit you on the chin, on the nose, on the ear, in ribs or on the elbow, wherever I want Carl that is where I'm going to hit you.
"Understand that and understand that now," Groves said in the direction of Froch. "I wish you the very best in your training camp because it's all systems go for me.
"The first fight, we went in believing, now we go in knowing and more importantly Carl Froch knows, he knows there is nothing he can take from the first fight, absolutely nothing apart from the gift that he was given in the ninth round by (referee) Howard Foster."
Froch is looking forward to fighting at the iconic Wembley stadium after enjoy a break away from the gym over Christmas.
He said: "Fantastic stadium, Wembley, (it) doesn't get any bigger than this; a platform for boxing and for myself to showcase my skills. I'm just so, so excited.
"Sky Sports Box Office and Wembley Stadium - it doesn't get any bigger than that. To be given this opportunity and I'm sure George Groves feels the same, it's a wonderful opportunity that we have to take with both hands."
"I've had an unbelievable break over Christmas and the New Year with my family," added Froch.
"But I've missed the gym, I've missed boxing, I've missed hitting the bag, I've missed listening to (trainer) Rob (McCracken), working hard on the road runs and that's bad news for George Groves because I'm now excited and looking forward to getting back in the gym and getting in the ring on May 31 and doing the business.
"The last time in fact I felt this mentally switched on and focussed was the build-up to the Lucien Bute fight and we all saw what happened there.
"I'm just enjoying it, so everybody else should enjoy it and Wembley Stadium, wow."
