Amir Khan has claimed Kell Brook's under-par showing against Michael Zerafa derailed their chances of an all-British super fight this spring.
Khan will instead fight Terence Crawford in an attempt to gain the WBO welterweight title, with the chance of a belt far too good to turn down for the Bolton-born fighter.
"I just feel that this has got the world title on the line, he's pound-for-pound up there as one of the best pound-for-pound fighters," Khan told Sky Sports News.
"The Kell Brook fight is there, still.
"After his last performance, it was such a bad performance his last fight, I just thought it maybe even hurt the fight between us both.
"When I had the opportunity to take this fight against Crawford, I grabbed it with both hands and said 'I'm going to take this fight', because it's such a big fight. Being a world champion and coming back and fighting Kell Brook would be awesome, would be even bigger."
After time away from the sport and a spell in the jungle on 'I'm A Celebrity', Khan is now 32 and well aware his chances of winning any more belts will be few and far between.
When pressed whether he really wants to fight Brook, Khan was in no denial.
"Yeah, definitely. I think that's a big fight that the public in the UK want," explained Khan.
"But at the moment, I think it's the Crawford fight I'm in now. I have to set my focus on him first, win this fight and then move on to Kell Brook.
"Somewhere down the line, this is probably the last chapter of my career in boxing. Somewhere down the line, the Kell Brook fight will be there, and I'm going to give it to the UK fans."
Will they, or won't they?
If they do, it will be one of the most anticipated fights outside the heavyweight division in history.
