AJ-Wlad II edging nearer

Anthony Joshua's next world heavyweight title defence could be confirmed 'pretty quickly,' says Showtime boss Stephen Espinoza.

The WBA 'super' and IBF champion is expected to face Klitschko in a rematch and the T-Mobile Arena in Las Vegas is the likely location for the proposed bout in November.

Klitschko is yet to confirm that he will take a second fight with Joshua, but Espinoza, who is executive vice-president of the American television network, hopes a deal will be finalised very soon.

"It feels like it's coming to a head," Espinoza told Sky Sports.

"Eddie [Hearn] is much closer to it at this point, but from my vantage point, I think a lot of the options have been explored and dismissed, and I think a decision is forthcoming pretty quickly."

Joshua completed a stunning victory over Klitschko in front of a large American audience, with Showtime splitting the TV rights with rivals HBO, and Espinoza feels 'AJ' can enhance his profile by making a US debut.

"It's no secret we've been salivating about getting him over here and certainly that would be a phenomenal fight," said Espinoza.

"It would be the biggest heavyweight Vegas fight in probably a couple of decades, so we would love to host it.

"That's a massive mega-fight wherever it is. For my money, the fight of the year so far. It was a star-making performance and for many here in the US, it was their introduction to Anthony Joshua.

"It is beginning to whet their appetite for seeing more."
