Usyk is pushed for a bit more of a contribution.

The Ukrainian is asked about what he has been drawing while up on stage.

He says it is his "homework" and then reveals it is a poem.

Asked if he can reveal it, he says "not now."

Finally we get to the fighters!

It's Oleksandr Usyk up first.

Usyk said: "Let's make history. Enough. Thanks very much."

And now Tyson Fury's trainer SugarHill Steward.

SugarHill's uncle Emanuel trained Lennox Lewis to his undspiuted heavyweight reign.

Steward said: "It's a lot more sentimental for me because I was raised around boxing my entire life. I watched the Kronk legacy and in the later years Emanuel [Steward] around Lennox Lewis.

"The heavyweight division is the grand division. It is what boxing stands for.

"You have the best two boxers facing each other. You can't get much better than this.

"If Emanuel was alive, he'd be right here, right now. I'm just blessed to be part of it and take what he taught me not just from boxing but as a man.

"Usyk is one of the best boxers and has been for some time, Tyson is too.

"I'm always going with my fighter for the knockout. It can be challenging or patient but I believe it will be a knockout."

Sergey Lapin, Oleksandr Usyk's trainer, is next to say his bit:

"This preparation started back in 2018 and it finished just one week ago.

"Today, Oleksandr Usyk is ready for the final belt in the heavyweight division.

"The size does not matter to him, what does matter is the opponent in front of him. I would love to wish patience to Tyson as it's going to be the most difficult night of his life."

Tyson Fury's manager Spencer Brown responding to Alex Krassyuk:

"His [Usyk's] team are a good bunch of people, we have a lot of admiration for them but come Saturday that goes out the window.

"We've already butted heads with his team and they are going to butt heads on Saturday.

"Usyk has a mountain to climb on Saturday.

"If I was you, I wouldn't worry about poets, I'd worry about your man on Saturday.

"Tyson is coming to take those belts. Our English boys have come from England to see him take those belts. The Fury army are here."

And now for a bit of poetry from Alex Krassyuk:

"I have one message to Tyson and his team, not to take it too close to the start.

"I have a short one from British classics from Henry Longfellow

"Be still, sad heart! and cease repining;"Behind the clouds is the sun still shining;"Thy fate is the common fate of all,"Into each life some rain must fall,"Some days must be dark and dreary."

While we wait for the promoters to finish their opening gambits, we can report Kal Sajad has officially been booted from his seat.

Over to team Oleksandr Usyk and his manager Alex Krassyuk.

"All has been accomplished, all has been spoken.

"There is only one assignment left and that's to pick up this green [WBC] belt and take it back home to Ukraine, the country it belongs to. Full stop."

Tyson Fury's American promoter Bob Arum is next up:

"In boxing, it's said, that the most important division is the heavyweight division.

"We have the opportunity to have an undisputed heavyweight champion crowned and it's very significant.

"The two participants in this fight have never lost. How great is that? How rare is that?

"Boxing fans all over the world will be focusing on the arena, on this fight and believe me it will be a great one."

Frank Warren is on a roll now:

"Every time he's challenged he does the business in style.

"He's never been beaten in 35 fights, he's just one the best heavyweights I've seen in my time in boxing and I think he'll confirm that on Saturday."

Tyson Fury's promoter Frank Warren is the first to speak after a little trouble with his microphone.

He's been handed Fury's mic to get us going.

"This is a great fight, it's the fight we've all been waiting for. The two best heavyweights in the world, both undefeated," he said.

"The two best heavyweights of a generation."

Events have been taking place all week to build up to this weekend's main event.

The Grand Arrivals, where all fighters strutted down the red carpet before taking to the stage for a brief interview, took place on Tuesday.

Yesterday we saw the open workouts where most fighters on the card were in the ring for three or four minutes but Tyson Fury was out there for over 20 minutes hitting pads.

And now it's time for the news conference with fans turning out to get a glimpse of the star duo Tyson Fury and Oleksandr Usyk.
