Agit Kabayel is open to defending his WBC heavyweight world title against Anthony Joshua, Tyson Fury or Moses Itauma.
When Oleksandr Usyk vacated his belts, Kabayel, the interim WBC titlist, was elevated to full world champion.
"He [Usyk] understands when he fights with Kabayel, this will be a hard fight for him," the German told Your Site. "This is my era."
Kabayel will now look to make the first defence of his title in September or October.
"For me it's no problem, I'll fight with everyone. You can call me. My phone is here, please call me, I'll fight with everyone," Kabayel said.
"I want competition, I will fight with the best ones. For me it's no problem. I fight everyone."
He added: "Tyson Fury, Anthony Joshua, when you think you have a chance to be a three-time world champion, let's do it. Kabayel will wait for you."
A former sparring partner of his, Kabayel knows Fury well. Fury, being ranked No 1 with the WBC below Kabayel, could force a fight with him at some point.
"We can make the fight but first of all I think all the fans, the British fans want to see the Anthony Joshua versus Tyson Fury fight and after that we can see who's best for the fight with me," the German said.
"First of all AJ [for Fury] and after why not? This is a big fight. We can make this also in Germany in a stadium. We can make this in the UK in a stadium. I think this is big, really big."
Itauma, only 21 years old but the rising star of the heavyweight division, could well be a future opponent for the new WBC champion, if he beats Filip Hrgovic when they clash next month in London.
"No problem. The winner of that fight versus Hrgovic, why not?" Kabayel declared.
"And also we can make a fight with Daniel [Dubois, the WBO champion] or Fabio Wardley. Anyone. For me it's no problem, I'll fight anyone.
"Send me the location, send me the date, I'm ready."
