Tony Bellew has warned David Haye to accept a rematch on his terms, or he will consider one of his "many options" instead.
Haye is currently recovering from an Achilles injury that he sustained during the stoppage defeat to Bellew in March and is hopeful that a return fight can take place before the end of the year.
Bellew is happy to honour Haye with a rematch but admits that certain terms must be negotiated and met, otherwise he will pursue other options - including a potential fight with WBO heavyweight world champion Joseph Parker.
Speaking to Sky Sports News HQ, Bellew said: "There's already been talks and negotiations for a rematch. I have so many options on the table and Haye is one of them.
"They want to do the rematch and I will do it in a heartbeat as long as the terms can be made and negotiated.
"If they can't be met, I have so many options, people have to remember that Haye needs me a lot more than I need him - I have nothing left to prove.
"I do love the thought of becoming heavyweight champion of the world, I'll be honest, I don't know if I'm good enough, but I'm willing to give it a go. Joseph Parker, I'm not playing around, I'm coming."
