Carl Froch says the lethal right-hand that knocked out George Groves in the eighth round at Wembley on Saturday was the "best punch of my life".
Froch settled the simmering rivalry between the pair and retained his IBF and WBA super-middleweight titles with a breathtaking hit that left Groves crumpled on the floor in front of 80,000 fans.
"That was the best punch of my life," Froch said. "You define a good punch from what it means, and what that meant was the whole George Groves saga and the history of the fight came to an end.
"People will look back in years to come and say that was the right hand that finished it all off."

Froch added: "I just threw it, I didn't really try to knock him out. I didn't load up, I just threw the punch and just landed it lovely.
"It was just a lovely pear of a shot and it closed the show and that's what world-class fighters do."
Froch had come under heavy scrutiny since beating Groves with a controversial ninth-round stoppage in November.
The London challenger claimed he had dominated that battle and predicted at the final press conference on Thursday that he would knock Froch out with a left hook.
Froch admits the hype surrounding the legitimacy of his first victory made the win at Wembley all the more rewarding.
"It's one of the most satisfying nights of my life - I've had the weight of the world on my shoulders," Froch said. "I've had George Groves in the back of my ear hole for the last year because he was in my ear for the Kessler fight in May 2013. It's now May 2014.
"I've boxed Groves twice in a year and I've just not heard the end of it."
