In terms of international diplomacy, it wasn’t Great Britain’s finest hour.
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 - boom. Kell Brook put an end to the entente cordiale with a verbal jab.
The Sheffield world champion, who defends his IBF belt on Saturday at Sheffield Arena, said his mission that evening would be “to break Mr Bizier’s heart...and break 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.
Bookies 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 won’t 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.
“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.”
