Tony Bellew has held "positive talks" with David Haye and his team over a potential rematch, but there are still options for his next fight, reveals trainer David Coldwell.

Bellew claimed the victory in their first match at the O2 in March, and talks of a rematch have been going around ever since.

During the fight, after dominating the first rounds, Haye tore his right Achilles in the sixth and was no more than a punching bag for Bellew for the remainder of the fight.

However, Hayemaker showed great spirit and did not give up, until his corner threw in the towel in the 11th round.

The two fierce rivals seem to have resumed negotiations recently as they attempt to agree a second fight. But, trainer Coldwell is still waiting to see whether both of them will formally agree terms for a rematch.

"They have been back and forth for quite a while now really I suppose, but I believe there are positive talks going on," Coldwell told Sky Sports.

"It is one of those fights that are possible. Whether or not it gets finalised or not, I'll believe it when I see it."

Bellew is targeting a return to the ring in December.

He sustained a broken hand himself and revealed after the fight that he would consider retirement, but is now training six times a week to keep himself in shape for another fight in 2017.

However, David Haye is not the only competitor available.

After Bellew decided retiring is not an option yet, he showed desire to fight pound-for-pound king Andre Ward or WBO heavyweight champion Joseph Parker, who defends his belt against Hughie Fury this month.

Even UFC champion Michael Bisping is considered as a possibility, as he responded to Bellew's challenge to meet him in the Octagon or in the ring.

"There are other options, but we're just seeing which one is the best one really," said Coldwell. "Best and most viable, that's what you've got to look at."

Yesterday, David Haye announced the details of the first Hayemaker Ringstar show, where his fighter Joe Joyce will make his pro debut. 

Haye, who turns 37 next month, has revealed that his return to action will take place before the end of the year.

Asked about a fight date in December, Coldwell added: "Yes, possibly. That's what we're hoping for."

If that is the case, a rematch with Haye looks most likely. Joseph Parker is about to fight soon, Andre Ward had two intensive fights in the last 10 months, and Bisping sounds more like a joke.

Given the emotion that first match (and especially the build-up) between Bellew and Haye brought us, a second battle under a different circumstances would be exciting!
