In just over a weeks' time, Anthony Joshua could have taken an almighty step towards becoming the undisputed world heavyweight champion.

Joshua is taking on Joseph Parker at the Principality Stadium in Cardiff, looking to claim the Kiwi's WBO belt to add to his current tally of three.

The Olympic gold medalist already holds the IBF and WBA world titles, as well as the unrecognised IBO version, having taken over the world of boxing with his undefeated 20-0 record, all of which by way of knockout.

Having dispatched one of the all-time greats in Wladimir Klitschko almost a year ago, 'AJ' can only be full of confidence ahead of the bout in south Wales next week.

He's fought in front 90,000 and 80,000 people in his last two fights, while Parker fought in front of less than a quarter of both of those when he beat Hughie Fury at the Manchester Arena in his last outing.

It is comfortably the biggest fight of Parker's career to date, and Joshua will be hoping his opponent gets overawed by the gravity of the situation come March 31.

The Briton, on the other hand, is already looking ahead.

That's not to say that the Watford-born fighter is taking Parker lightly or for granted, but merely that he has so much confidence in his ability that it makes sense to plan for the future.

And the main target is WBC world title holder Deontay Wilder, in order to become the undisputed champion of the division.

It was thought for a while that the 'Bronze Bomber' may have been in the firing line before Parker, but a deal couldn't be reached, and he instead went on to knock out Luis Ortiz instead.

With history at stake, it is hoped that the two will be able to come to an agreement if Joshua gets past Parker, but he insists Wilder will have to make his demands much more realistic, as he is the bigger name.

"If he was serious about the fight, we'd do serious negotiation. If not, (he should) stop hooting and hollering because we'll just freeze him out," he started.

"We're in a position where I've still got great top-10 challengers I can compete with. He's in a position where the broadcasters ain't interested in (him fighting) Joe Bloggs anymore.

"I know where I am going with my career. If he wants to be a part of this and jump on the train and come to the UK, he has to be realistic and stop living the fantasy. That is all we are saying, be realistic in negotiations.

"What we've got to offer is going to be 10 times more in terms of financials - because that's what it comes down to - than he's looking at in America.

"If he offered me 10 times more money to fight than what I am looking at in the UK, I would go there to fight him. But he is coming here. We are doing the offering, he hasn't offered us. Take it or leave it."

Joshua certainly has a point with regards to the lack of interest in America, as his promoter Eddie Hearn demonstrated back in November, in a video where he asked people in Ney York if they knew who Wilder was, as you can see below.

Clearly, the American needs to come back down to Earth a little with his demands, as Joshua's profile is far superior to his.

However, the Briton dispatch Parker accordingly a week on Saturday before these discussions can even become a reality.
