"I can seriously say I feel the best I have felt in my whole career.

Desperate to make an impact in the hyped heavyweight market there, Parker knows a win will set up lucrative clashes while a loss will be a disaster.

"This is pretty much a make or break fight. You win this fight and it's on to bigger fights but if you lose you have to start again so I am just focused on this. Hopefully I get it done and then I can move forward," Parker told Boxing Scene.

Fury's father and trainer, Peter Fury, gave a frank interview with BWTM Sports on Friday where he offered plenty of praise for Parker – along with a few warnings.

"I think he probably brings more of a threat than any heavyweight out there," Peter Fury said of Parker who is 23-0 with 18 knockouts as he puts his belt on the line for a second time.

While the promoters for Kiwi heavy-hitter Parker, Duco Events, control rights for New Zealand - where the fight will cost $39.95 via Sky Arena - Australia and Samoa, Fury's promoters Hennessy Sports have opted for a different route in their part of the world.

With no broadcaster secure and the bout for the WBO belt less than three weeks away, the organisation announced on Wednesday (Wednesday night NZ Time) the rights for the UK and Ireland had been secured by YouTube.

Parker's low profile in Britain – this will be his debut there – always put a question mark about this being a blockbuster fight. But Fury's inability to draw a home crowd has some perplexed.

The Manchester Arena has a capacity of 21,000 for boxing. But Fury's promoters aren't even trying to sell seats to the second tier which holds nearly nine thousand.

Fury has been talking tough in the leadup to the fight and ramped that up when asked for a prediction for his victory.

"Four rounds I would say. Four rounds ... knock out," he told WOTV. 

Parker has also voiced his determination to score a knockout win and hammer home his abilities to the British market where he believes bigger fights lie beyond Fury.

Boxing is never short of promotional stunts but the lanky Brit seems to be pushing his cause a bit too far ahead of the September 23 clash in Manchester.

He's been running around Windermere in Britain's famous Lakes District in army fatigues and now he's doing Sylvester Stallone impersonations.

Fury lined out for a training session/photo shoot at a local abattoir, doing his best to replicate Stallone's Philadelphia scene from the first Rocky movie which Fury says remains one his his favourites.

Daniel Dubois is regarded as the next big thing in the buoyant British heavyweight boxing scene.

The 19-year-old has turned his back on a shot at the Tokyo Olympics to go professional and has cruised through his first four fights with consecutive knockout wins.

But it's in the sparring ring where he has also made his mark, knocking down Joshua while helping his fellow Brit prepare for his recent win over veteran Wladimir Klitschko to add the WBA belt to his IBF title.
