Heaney is promoted by Frank Warren and knows Saturday’s show is another chance to prove his popularity in his own backyard is a strong as ever.
“It sold out immediately – I could’ve sold it four times over,” Heaney said.
“So win and it will remind Frank Warren why he signed me all those years ago
“The only fight I will have after Saturday is a fight at Stoke City in a year’s time. No fight in between.
“I get why they would want you to fight in between – to stay relevant – but I’ve explained that doesn’t matter. It would be the biggest sporting event our city’s ever seen outside of football.
“Saturday is my last ever fight if I can’t get the stadium.”
Heaney, who has won 18 of his 21 fights, says it is “strange” to be talking about retirement but knows his hand will be forced if a date at the home of the Potters cannot be finalised.
“Make no mistake, the plan is to win on Saturday and to have that final push to give the city what it deserves,” he said.
“We’ve filled up every area we’ve ever been to for the last five years, it’s outrageous.
“I deserve it. I love fighting for Frank so, best case scenario, we fight next year at the ground.
“Worst case, I win and say ‘thank you’ and go out into the King’s Hall and take one final bout.”
