Brook told Sky Sports: “I’ve got to the stage now where I just want to sit down and try and make the fight, instead of trying to strangle him!
“I would rather sit down and talk about the fight, what’s holding it up. What we can do to get it across the line. That’s all I would be interested in, because the fans are missing out.
“I want to fight December, [then] February or March. It would be ideal for us to fight then.
Asked about a venue, the Sheffield fighter added: “It don’t matter to me as long as he’s opposite me.”
Matchroom Boxing boss Hearn is currently putting together an undercard for Joshua’s second world title fight against Ruiz Jr and Brook has welcomed the chance to showcase his skills on such a big stage.
“Yeah, I believe I can fight on that,” said Brook. “It’s something different, it would be a different look. I know that I would be ready for that time.
“It will be a year by the time I get in, so I don’t want an elite fight, but I want a good fight just to dip my feet back in the water.”
