Amir Khan's proposed fight with Kell Brook has been years in the making.
The question is why Eddie Hearn, promoter of both men, has never been able to bang their heads together and get a deal done.
More specifically, it has to be asked who is dodging who.
Khan has faced criticism, including from Billy Joe Saunders, for avoiding a British super-fight with Brook, which many still hope will happen in 2019.
However, just a matter of days ago, the former Olympic silver medallist revealed - albeit wrongly, it seems - that there had been a breakthrough in negotiations.
"He's agreed to be 147, and also have a rehydration clause of 10 pounds. I'm happy with that," Khan said.
Brook quickly tweeted that he had agreed no such thing, casting renewed doubt on whether this bout is ever going to happen.
In an interview with Behind the Gloves, the Sheffield-born fighter has now elaborated on Khan's claims, launching a tirade against his rival in the process.
Brook has responded
"He's saying that he sparred with me many years ago and he had to use one hand to destroy me, that I'm a very very easy opponent for him," Brook said.
"He wants me to only put 10lbs on, even though there's no world title on the line, there's no IBF belt on the line...
"He's a b**** h***, he's a little b****. If he takes the fight, he's going to have to take the fight because everyone's looking at him thinking, 'what are you talking about Amir?!'
"You're saying come to 147 [lbs], do this, do that...and even still he's making things up, saying I agreed on this 10lbs thing, why would I agree on that? It's a joke.
"He's a joke. He's a joke. He's robbing the British public, robbing the fans of the fight, what we all want.
"The bottom line is I'm the welterweight king in Britain, so don't claim that you are unless you get in there with me."
It sounds as though Brook is resigned to the Khan fight falling through. He added:
"There's many options, there's Manny Pacquiao. Everyone's going on about Amir Khan, when I started from day dot with Eddie Hearn, when it was me, Carl Froch and Darren Barker. [Hearn's] loyalties lay with me.
"If anyone's getting the Manny Pacquiao fight, it's me."
Khan has indeed talked up the possibility of himself facing the veteran Filipino.
Yet, at his last fight - a points victory over Samuel Vargas - it was Brook who was ringside, demanding he is next to face him.
Only time will tell if he gets his wish.
