Everything had been going well in the Kell Brook v Kevin Bizier, Britain v Canada, press conference at Bramall Lane.
Promoter Eddie Hearn had extended a warm hand of welcome to the French Canadian party.
In return his opposite number Yvon Michel spoke admiringly of the way Britain was boxing above its weight in several divisions.
Then Kell Brook put an end to the entente cordiale with a verbal jab.
The Sheffield world champion, who defends his IBF belt tomorrow at Sheffield Arena, said his mission that evening would be “to break Mr Bizier’s heart...and his bones”.
Brook said he was “desperate for an old-fashioned war” with the visitor and wanted to excite the 7,000-plus fans who will be cheering him on – and doubtless upset customers in the 180 bars around Quebec City who will be watching on pay per view.
Bookmakers think Brook will have little trouble – one has given 66-1 against the north American, who fought in Liverpool in the amateurs.
But outside influences will not worry the South Yorkshireman, who sees himself approaching a crossroads in his career. “I am IBF champion of the world and I want to show everybody why. I always rise to the occasion, always find a way. I am 30 this year and want to show the world I am the best and am ready for the big fights.”
The champion said he was “born” for moments like his Arena ring walk accompanied by “All of the Lights music”.
He added: “To hear and feel the fans, walking closer to the ring, it makes you feel invincible” he says.
“I am going to get in the ring and enjoy the night.”
Meanwhile, Gary Sykes has warned Luke Campbell that he is not fighting to make up the numbers and will hand him a second professional defeat as they clash for the vacant commonwealth lightweight belt on the undercard tomorrow night.
The Dewsbury fighter steps up to lightweight having held the British and English titles at Super-Featherweight.
A clash with Liam Walsh for his British belt and the vacant Commonwealth strap ended in defeat and showed Sykes that he needed to move up, and he wants to prove he can make an impact at 135lbs and he is no stepping-stone for Campbell.
“I don’t like the gatekeeper tag,” said Sykes. “I don’t think it reflects me or reflects what I am.
“I am not there to make the numbers up and they’ll get the best of me that is possible.”
