It brings together two unbeaten young protagonists, the 2012 Olympic champion Joshua, 28, a Londoner of Nigerian heritage, and Joseph Parker, 26, a Samoan-born New Zealander, in a genuine unification bout involving four titles.

Traditionally there has to be a war of words to help boost ticket and pay-per-view TV sales but in this case any animosity will need to be manufactured because, basically, both are nice chaps who do not harbour hate for each other and regard their spat as strictly business.

So should they feel the need to put some passion into their verbal exchanges, perhaps they should peer beyond the punch-ball into the world of football.

For there is a rare old headline-grabbing scrap going on between two Premier League managers which would have any fight promoter drooling with delight.

Jose Mourinho v Antonio Conte is a veritable bill-topper in terms of expressing unabated dislike for each other in a firecracker of a feud.

Handsome Chelsea boss Antonio Conte, usually the epitome of cool, lit the blue-touch paper by branding Mourinho "a little man" and "a fake" after the Manchester United manager mischievously made reference to his Italian rival's match-fixing controversy - over which Conte was cleared - long before he took charge of Mourinho's former London club.

Astonishingly, he said Mourinho had dementia and that he had nothing but contempt for the Portuguese man ’o’ war.

Then Mourinho countered: "I think when a person insults another, you can expect a response or you can expect contempt, silence.

"The first time he insulted me, I had a response that I know that touched the point where he really feels hurt.

"Then he insulted me for a second time, but now I change. For me, contempt means end of the story."

But is it?

As the BBC helpfully have chronicled:

• January 4: Mourinho says he did not need feel the need to behave as a clown during games
• January 5: Conte suggests Mourinho should remember how he used to behave
• January 5: Mourinho says he will "never be suspended for match-fixing/does not name Conte, who served a four-month ban at Juventus during 2012-2013 for failing to report match-fixing at his previous club Siena, but was cleared of any wrongdoing by a court in 2016
• January 6: Conte hits back by calling Mourinho "a little man".
• January 9: Conte says Mourinho "used serious words" and warned: 'I will not forget this'.

However, this month's exchanges have not been the first between the two bosses.

• October 19, 2017: Conte says Mourinho needs to "look at himself" and stop talking about his former side
• July 29, 2017: Conte says that he must avoid "a Mourinho season" as the champions attempt to defend their Premier League title.
• March 14, 2017 Mourinho tells Chelsea fans "I'm still number one" after being heckled during his side's FA Cup loss at Stamford Bridge
• February 12, 2017: Conte says he does not like Mourinho's "joking" after the Manchester United boss said Chelsea cannot be caught because they are a "defensive team"
• October 23, 2016: Conte says he was "not mocking anyone" after appearing to antagonise Mourinho in Manchester United's 4-0 defeat at Stamford Bridge

Mourinho, of course, is the Marmite man of football. You either love him or hate him. There is no in-between. 

Unashamedly, I fall into the former school because I love characters who enliven sport and I believe football would be poorer without him.

Mean, moody - though not quite so magnificent this season with United as like Chelsea they are forced to chase the slicker Man City.

He can be objectionably crass, but he can also be a charmer and is a proven winner and the ultimate enigma.

But back to that other big fight.

Last week I received a large dollop of derision from certain quarters when I suggested here that Joshua was by no means a cast-iron certainty to beat Parker who, we learn, likes to go fishing for snapper, bite their heads and eat them raw.

I stand by my forecast. Should the cute Kiwi get his teeth into British boxing's biggest fish it could be Joshua who tastes defeat for the first time in his pro career.

In the meantime, I remain hooked on Mourinho v Conte, a big fight with bite.
