Watch as Tyson Fury, while dressed as a Mexican wrestler, calls Otto Wallin a "bum" at the weigh-in ahead of their Las Vegas fight.

WBC president Mauricio Sulaiman has tweeted saying there will be a special Mexico-themed belt up for grabs as well...

With the contest falling on Mexican Independence Day weekend, fight week has seen Fury dressed as a Mexican wrestler, serving tacos in a Mexican restaurant and delivering phrases in Spanish to the media in a bid to maximise the non-title bout's profile in the States.

Fury has tried to align himself with Mexican fans, who have travelled to Las Vegas for the weekend. He has repeatedly referred to himself as "El Rey Gitano", which means "The Gypsy King".

At one point in the news conference, Fury was challenged by a reporter to understand a question asked in Spanish. After at first offering a stock answer, Fury concluded: "And yes, I do love cuddly toys and crayons, thank you for asking." His answer drew widespread laughter at the MGM Grand's Studio Ballroom and Fury then told the next reporter poised to ask a question that he could only understand if it was asked in Spanish.

"I wasn't supposed to box on this weekend," Fury added. "When we heard Saul 'Canelo' Alvarez would not be fighting in Las Vegas this weekend I thought what a shock. This has been a special weekend for many years. I thought the Mexican people will not have a main event so I brought my fight date forward four weeks."

Tyson Fury splits opinion.

What no one can really grumble with is the work he puts in, not as a fighter but a salesman.

This week he has done hundreds of interviews, had camera after camera shoved in his face and even done interviews while he was meant to just be eating his dinner.

It has been relentless. Thankfully, he is larger than life and continues to draw smiles when others may simply want a lie down.

He might just be, right now, the best Fury we have seen.

That includes the Fury that got in the ring with Wladimir Klitschko in 2015. He looks faster, slimmer and is clearly better mentally. He is getting close to optimum.

What a transformation. Not too long ago, this man was 28 stone...

Now he's in the best fighting shape of his career...

Sweden's Wallin has been written off but his team say he will "attack" the "obvious" flaws they see in Fury.

But Wallin, a 6ft 5in southpaw with 20 wins from as many fights, has brought a psychologist with him to prepare and is wary of Fury's mind games.

"We are aware of how Tyson gets in people's heads and can throw them off," said Wallin's trainer Joey Gamache, a former two-weight world champion.

"We have talked about not falling into those traps.

"We know we are in there with the best heavyweight out there, a fighter who is very unorthodox. But we see openings that are pretty obvious and will attack those openings."

Here is an image of a lion, the Empire State Building, the Statue of Liberty and a rollercoaster. It kind of sums up the madness of this city. We ain’t on safari and we certainly ain’t in New York.

If you’ve never been to Las Vegas I highly recommend you swing in for two nights. The desert sun bakes you, the pools are packed and revellers walk around all day clutching weird-shaped plastic cups full of drinks of weird colour.

You won’t like it if rolling green hills or historic artefacts are your thing. If you’re all for a beer, bet and belly full of unhealthy food though then this might just be your heaven.

The Plazzy Scouser: Tyson Fury, man has passion. Might not be the most technical boxer. But he has heart.

TJ8488: Wilder. Giving Fury a concussion and koing a fighter as skilled as Ortiz over anything the others have done.

Luke King: Tyson Fury. Has the best win over the best opponent.

Fury said: "Is Wallin knocking me out? Definitely not. I don't know much about Otto and sometimes that is a good thing.

"Sometimes when you know a lot about an opponent it doesn't turn me on fully, when it's unknown, it's more exciting.

"I feel good, fit, have trained really hard, weight is perfect, injury free, sharp, rejuvenated. I feel ready for a good fight. I am as strong as I have ever been."

Otto Wallin had never been to Las Vegas before this week. Talk about a baptism of fire.

He’s brought over 20 pals with him for what will be a bit of a wild ride. When I spoke to him two weeks ago he told me he didn’t know what plans they’d make after the fight but was certain they’d find a party or two.

The big Swede has a tough night on his hands but he’s handled fight week impeccably, doing all the media asked of him and remaining calm when faced with the chaos that surrounds Tyson Fury.

Anthony Joshua says Andy Ruiz is currently the best heavyweight in the world.

Joshua is seeking to win back the IBF, WBA and WBO titles from the Mexican fighter when the pair meet in their rematch on 7 December in Saudi Arabia.

Will the winner of that one then go on to face Fury?

Wallin was a key sparring partner for Anthony Joshua. He is not unknown but looking online he does look slow on his feet, so he will be beaten for speed, variety and class, it seems.

No result will favour Fury in terms of the hard-nosed critics of the opponent and we understand that.

But if he gets it done with minimal fuss and we get to Wilder, then no-one will remember the ordinary fights if the big ones come around often enough.

US promoter Bob Arum pointed to the inspiration Wallin can draw from the shock caused by Swedish heavyweight Ingemar Johansson in arriving in America to stun the legendary Floyd Patterson in 1959.

Wallin replied: "I come from a small place in Sweden and now I'm on the big stage. I've dreamed of this and am willing to put it all on the line.

"I'm well schooled, I have good offence, defence and I think I have what it takes to cause an upset."

So who is Otto Wallin?

Well, he's a 28-year-old Swede who has fought 20 times in his professional career and has won them all.

However, a closer looker at his record shows no real top level names to speak of.

But this is heavyweight boxing. Anything can happen. Remember, everyone wrote off Andy Ruiz earlier this year before he stunned Anthony Joshua.

Will we see a similar shock again tonight?

Earlier this week myself and Steve Bunce went to interview Tyson Fury at the house he’s been renting.

It was a hell of a listen as he opened up about finding happiness, celebrities in his phone book and his amateur days.

You can read the best bits by clicking here.

Banter was flowing as his team around him repeatedly wound one another up, so much so you had to keep a sharp eye as you felt anyone could end up being thrown in the pool at any time. In the end, only Fury ended up in there.
