Britain's best lightweights Kevin Mitchell and John Murray have both promised war when they meet at the ExCeL Arena on Saturday 9th July with a world title shot on the line for the winner.
The pair came head-to-head today at a press conference in London to confirm their Battle of Britain showdown for the WBO Intercontinental lightweight title.
It followed an explosive meeting in the ring on Saturday night at the O2 Arena when they were announced to the crowd.
The show, titled North 'n' South, will be a Frank Warren Promotions event, but Warren's sons Francis and George will be doing much of the organising.
"This will be an absolute classic," promised former world title challenger Mitchell.
"I let myself down, my family down and my fans down when I wasn't properly prepared for the Michael Katsidis fight.
"I've got another chance now against Murray, and I plan on taking it.
"Murray's a great fighter and I have got massive respect for him. But when I am at my best, I will beat him.
"I think DeGale-Groves wasn't as explosive as people thought it would be.
"But this will be more explosive. Forget about fireworks, me and John are going out there to throw bombs. If I lose it will be hard to come back, that's why winning is my only option."
But Murray, who has vacated his European title in order to focus on Mitchell, hit back by promising victory.
"I've seen a lot of Kevin's fights, and I am preparing for the very best he can possibly be," said the undefeated Mancunian.
"But even that won't be good enough.
"I am hungry and I am strong, and I will answer fire with fire on July 9.
"I don't care that I am coming into Mitchell's backyard, it will just make it all the sweeter when I knock him out.
"We're not like Groves and DeGale, we don't hate each other. In fact, I like Kevin and he likes me.
"But business is business and we'll be going at it hammer and tongs at the ExCeL. There is so much at stake here that just like Kevin, losing is not an option for me."
Francis Warren and brother George were excited about the fight.
"This is a great opportunity for both guys, and the winner will definitely be looking at a world title shot within 12 months," they said in a joint statement.
"We've been working on this fight for a long time, so it is fantastic that we've finally got it on.
"Everyone wants to see the best fighters in Britain facing each other, and here you've got the best two lightweights in the country meeting with a world title opportunity on the line.
"We're sure the show will sell out, and we're aiming to get a crowd of around 12,000 into the ExCeL Arena for a brilliant night of boxing."
An action packed undercard will be announced shortly.
