Carl Froch settled his rivalry with George Groves in brutal fashion as he knocked his bitter enemy out cold with a crunching right hand in their record-breaking Wembley Stadium rematch.

Froch infamously won their first meeting in Manchester last November, recovering from a first-round knockdown and terrible start to stop Groves controversially in the ninth round.

He once again retained his IBF and WBA super-middleweight titles and answered any remaining questions with a breathtaking eighth-round punch which knocked Groves out in front of 80,000 baying fans.
