British cruiserweight champion Isaac Chamberlain is not certain he will fight Viddal Riley next.
Riley made his name training KSI in previous years, but has established himself as a professional, and is currently the England champion at the same weight.
He defended his belt with a win against Mikael Lawal at the weekend, and Chamberlain told Sky Sports that he wants Riley next.
He said: "That's what you've been calling for. It's a big fight, big hype.
"Let's go now. You've had your little comparison, which failed, miserably. Let's go. Let's go now. That's it."
However, he made it clear he had options.
"It makes me wonder, you lot are flaky, you lot are weird," Chamberlain continued.
"I can always go and fight Chev Clarke [his mandatory]. They haven't sent an offer yet. They'll probably send it one day before the purse bids or something. The [European champion, Michal] Cieslak option is already there."
