If you didn't see the aforementioned altercation between Dubois and Joshua back in June, hit play on the video above to see how it unfolded.

We saw contrasting styles during Thursday's news conference with Dubois seemingly eager for it all to end and Joshua happy to entertain multiple questions with in-depth answers.

Dubois was sharply dressed in a well-tailored blue suit, while Joshua was much more casual in a tracksuit and his trademark one AirPod in his right ear.

How much you can read into the body language remains to be seen - Dubois have never been a great talker - but it will be interesting to see if Joshua's courteous and respectful approach got under the skin and in the mind of his rival.

One of the questions centred on reports that Dubois floored Joshua during a sparring session several years ago.

Dubois answered: "It was sparring, now we're fighting, this is different.

"Move on", he added before banging on the wooden table.

There was also a question about their altercation in June when Joshua was anything but calm as he threatened to throw a chair across the face of Dubois.

"You should never let anyone take an inch because they'll end up taking a mile," replied Joshua. "You know what I mean Dan?"

But Dubois, vacantly, replied: "Sorry?"

Did we expect Liam Gallagher to be inside the ring performing? Well, he's not. He's on a stage staring out at 96,000 people. What an incredible sight.

It's fair to say Dubois is not quite the household name of his rival Joshua.

So, in the interest of trying to give you more of an insight into the 27-year-old, we've pulled together a few stories, ranging from his childhood and learning the art of pugilism through to his antics in the build up to tonight's fight.

I'll bring you a few snippets over the next 30 minutes or so in this series that I've boldly named 'Dubois Diaries'.

First up, did you know that Dubois was home-schooled and could complete five hours of push-ups a day from the age of five?

The things you have to do to become an elite level boxer, eh?!

Dubois' absence from mainstream schooling might explain why he was so timid when he first entered the world of boxing.

He was an introvert with little time for friendship or socialising.

When Dubois found himself in the limelight of pro boxing as a 19-year-old, he struggled to adapt.

During his first interview to Queensberry Promotions, having signed for Frank Warren's stable, Dubois turned to his father for support for almost every question when asked to share his dreams and aspirations.

In true Rock n Roll fashion I'm not halting this live text for Liam Gallagher.

Updates on how it's playing out are coming but I'm sticking with big fight build-up.

All on board?

Liam Gallagher is looking more and more like Ronnie O'Sullivan every time I see him.

Here we go then. After a decent wait, Liam Gallagher has been introduced to the Wembley crowd by Michael Buffer.

He gets going with 'Rock n Roll Star'. Tune!

As Liam Gallagher famously sings, you've gotta roll with it, you gotta take your time.

It seems he's taking a leaf out of his own book by keeping us all waiting as he takes his time to head to stage.

We're hoping he makes his Wembley entrance pretty soon.

We had about two hours to wait for the fighters to arrive at Tuesday’s grand arrivals at the Odeon in Leicester Square. I decided to find somewhere quiet and catch up on emails.

I was directed through some doors, but did not expect to be cosying up on the back row of the stalls in the cinema's marquee room.

Think they missed a trick by not playing 'Rocky' on the screen.

When you come out, there is a sea of faces and so many lights and phones pointed at you. Some people naturally relish it. Some people are like a deer in the headlights. I hope that Dubois performs.

This all becomes noise and you have to focus in on the one person in front of you.

Many have suggested that Dubois is not the true IBF heavyweight champion - it's all a little Game of Thrones.

But Dubois currently sits on the Iron Throne after Oleksandr Usyk was forced to vacate.

Usyk held the IBF along with the WBO, WBC and WBA belts after beating Tyson Fury in May, becoming the boxing's first four-belt undisputed heavyweight champion.

However, the Ukrainian agreed to a rematch with Fury rather than facing mandatory IBF challenger Dubois, who later went on to win the interim title after stopping Filip Hrgovic.

Just over three weeks after that victory against Hrgovic, Dubois was handed the outright belt and all the glory that comes with it, although he admits that receiving the honour without beating a champion doesn't look great.

"I need to retain this world title," Dubois said at Thursday's news conference.

"It's a great thing to have but I need to legitimise myself by winning this fight.

"I'm on the rise, I've got the momentum on my side. No more words - just fighting, punches. I'm ready to fight and destroy. Destroy."

Love this story and bang on theme. We're still patiently waiting for Liam to grace us with his presence at Wembley.

UFC star Conor McGregor speaking to BBC Radio 5 Live: "It's great to be here and witness this spectacle firsthand. It can go either way, it's a good close fight. They've sparred with each other before and it's going to be a dust-up in this mega stadium."

On potential stadium fight: "A stadium show has been an ambition for a long time for sure. Some time in 2025 [next fight]."

On Fury v Joshua: "Tyson is lightning, he's fast on his feet. it's a cracking fight, it must take place no matter what takes place tonight, tomorrow or the day after."

I can confirm that Wembley Stadium is now full and rocking. We have 96,000 fans. We have Liam Gallagher. And we have two Britons fighting for a world title.

There is nothing quite like it.

Dubois spoke about resurrecting his career earlier this week but he's not the only one in tonight's main event to have rebuilt.

Following back-to-back defeats against Oleksandr Usyk, Joshua has won four in a row to get back to the top table.

His most recent win came against former UFC heavyweight champion Francis Ngannou, who was competing as a boxer for just the second time, and doesn't provide too much insight as to improvement.

However, Joshua's three victories prior to that knockout win against Jermaine Franklin, Robert Helenius and Otto Wallin, all suggest he has gone back to the drawing board to ensure his career doesn't fizzle out.

I've got a boxing adjacent, bumping into a famous person one for you.

I was in Las Vegas for a Tyson Fury fight, can't quite remember which one at the moment. It's tradition for UK media to have dinner with the UK promoter, should they be running the show. So Queensberry's Frank Warren took us all to Gordon Ramsey's restaurant.

I was sat next to the legendary promoter, enjoying my weight in fresh burrata when Mr Ramsey came over and started chatting to Warren. They're old mates and Ramsey is a massive boxing fan. I was a bit star struck considering myself and my then roommate had spent much of our free time that summer binge watching Kitchen Nightmares.

And Ramsey, if memory serves me right, comped the entire meal. Top gent.

The camera just panned to magician Dynamo. Or did it???

When former undisputed heavyweight champion Lennox Lewis speaks, you have to listen.

Watch his main event prediction below.

Chris Eubank Jr
British middleweight boxer

When you are a marquee name like Anthony Joshua, there is no 'this is it'.

'AJ' is a maverick. He has been able to do things nobody has done. He has paved the way for other fighters.

He could lose to Daniel Dubois and everybody would still want to see him fight Tyson Fury. That will not change.

Of course, defeat will be damaging to Joshua's reputation and career but it is not something he could not bounce back from. He has done it before.

To keep the momentum and wider interest in the bigger fights going, however, he has to win, and I think he will.

Joshua is too experienced, too strong and his boxing IQ will be too high for Dubois. It is a cliche but there are levels to the game and Joshua is just a few too many levels above Dubois.

The exciting thing about heavyweight boxing, though, is that they are so big, strong and powerful that even when there are levels, all it takes is one punch and it is over.
