Anthony Joshua is hopeful that Wladimir Klitschko will be available for a rematch of their epic fight in Wembley in April.
Joshua had knocked Klitschko out in the 11th round, and wants to fight the legendary boxer again, this time in Las Vegas.
Speaking to Sky Sports, the Watford-born fighter said: “The last fight put the expectations on a pedestal but it was entertainment.
“We can’t fight too many fights like that but regarding who I’m fighting, I’ve got two options.
“One is a rematch with Klitschko, and we’re waiting to see, and we’re trying to dangle a few carrots to make him bite and spark is interest again.
“The man has achieved great things throughout his career so it takes a lot for him to get motivated and interested again.”
Joshua also believes Vegas would be the perfect place for such a fight.
“Vegas – it is the Mecca of boxing, and this is an opportunity,” Joshua said.
“People wouldn’t mind travelling, and it is a nice big hurrah for himself. He has achieved so much, does he have the motivation?
“I think Vegas will get his blood boiling again.”
If Klitschko decides to retire, Joshua will have to face mandatory challenger Kubrat Pulev to defend his IBF title.
He added: “When you have a belt, there’s mandatory positions you have to face and one of them is Kubrat Pulev, a very talented Bulgarian fighter.
“If I don’t fight Klitschko, this is the other guy I’ll have to compete with in the future.”
