Carl Froch believes his bitter rivalry with George Groves was career-defining.
The four-time world champion has announced his retirement from professional boxing and will now join Sky Sports as a pundit.
Froch's farewell fight turned out to be his historic Wembley win over Groves on May 31, 2014. He believes that bout, along with the first meeting in Manchester six months earlier, and the fall-out of both, will be a major part of his legacy.
The first fight's controversial ending as well as the Rubik's Cube, the shove at Wembley and the "is he going to cry?" quote from Groves on Ringside were memorable moments in an intense and at times unpleasant rivalry, but 'The Cobra' is happy to admit it is what he will be remembered for.
"George Groves I in Manchester was such a tough fight, such a great fight for the fans, for George, for me," he told Sky Sports.
"We all did ourselves proud and you couldn't have written the script for what happened. The script couldn't have been better. It's just amazing these things happen.
"It just set up the biggest rematch in post-war British boxing.
"Then to transcend the sport over to a whole new audience for me, on that platform and the way to finish it, in such a conclusive manner, was so satisfying.
"That is my defining moment."
Froch worked ringside for Sky Sports when Groves returned the ring in September following that Wembley knockout.
He beat Christopher Rebrasse to be crowned European champion and then called for a third fight with Froch.
The Cobra, who simply called out '2-0' in response, says that he may never see eye-to-eye with his fellow British fighter.
"Certain personalities do not get on, so George Groves is never going to be my best friend, " he said. "I'm not sure he'll ever be my friend."
