Anthony Joshua is about to get back in the ring, after he sent Wladimir Klitschko into retirement  earlier this year in front of a record 90,000 crowd at Wembley.

Joshua's next opponent for the heavyweight title is Kubrat Pulev (25-1, 13KO) and the fights is scheduled for October 28 in Cardiff, Wales.

Promoter Eddie Hearn believes this fight will be another record breaker with up to 80,000 people expected to fill Cardiff’s Principality Stadium.

Hearn is confident Joshua will break the stadium’s current boxing crowd record of 55,000, which saw local hero Joe Calzaghe beat Mikkel Kessler in 2007.

“I’m delighted that we will be in Cardiff at the magnificent Principality Stadium for the next step of the AJ journey,” Hearn stated.

“Nearly 80,000 will gather on October 28 to create another unforgettable night of boxing. Get ready for the next episode from the biggest star in world boxing.”

Hearn believes the O2, which was a preferable venue for Joshua before, is no longer big enough to host him because he has grown into a stadium fighter. And the heavyweight king promised his fans a “spectacular night”.

Joshua (19-0, 19KO) turned to fans in an emotional video.

“October 28 can’t come soon enough. I’ve been eager to get back in the ring since Wembley and now we’re confirmed and ready.

“I’ll be locked away, focusing on fight No.20 for the next eight weeks. I’m excited to experience the atmosphere in a sold-out Principality Stadium and aim to give the fans a spectacular night.”

Joshua is the biggest catch in the heavyweight division right now and offers fly from every corner.

However, Kubrat Pulev is the first on the list, as he is the IBF mandatory challenger, and has been for around a year. He was even willing to wait a bit longer for a Joshua-Klitschko rematch before he gets his chance.

Now that it is his turn to deliver, the Bulgarian insists he will not be just another of Joshua's victims.

Kubrat "The Cobra" Pulev, 36, is a two-time European champion with his latest victories coming over Dereck Chisora, Samuel Peter, and Kevin Johnson.

“Anthony is formidable. We will not hug and hold, we will not run - we will stand and fight." Pulev revealed about the upcoming fight.

“His style fits mine perfectly and in boxing, styles make fights. My preparation will be very intense, and I will be perfectly ready when I enter the ring so that he will have no chance to beat me.”

Pulev’s promoter Kalle Sauerland sees Joshua's lack of experience as his main weakness.

“Anthony is a great champion and his last fight ignited the division,” said Sauerland. “But by his own admission, he is still learning and Pulev is not the sort of opponent you want to learn against.”

Experience is on Pulev's side, but many see him as an obligatory fight for Joshua, before AJ turns to Luis Ortiz or Deontay Wilder. Kubrat Pulev's only loss came in 2014, when he was knocked out by Klitschko in the fifth round.

On the contrary, Joshua's latest and most impressive victory came against the exact same opponent via 10th round KO.

"Styles make fights," like the Bulgarian says, so 20-0 or a huge upset, is yet to be seen.
