Both men had gone into the fight looking to hit back after they suffered their first professional defeats in their previous outings. But Froch executed his fight plan perfectly, which was reflected in the scores given by the judges of 119-109, 120-108 and 120-108.
Froch said: "It's fight after fight here, which is risky. I can't just sit back in Nottingham and defend my title against bum of the month, no disrespect to any journeymen. I have to get in there and fight Glen Johnson and potentially Andre Ward, a WBA champion and top American and Olympic gold medallist."
Froch told BBC Radio 5 Live: "I'm not messing about: I'm in this sport because I mean business and I want to secure my legacy as a legend in the sport and I think I am getting something close to doing that. Hopefully one day British television might show one of my fights."
Froch got the chance to fight for the title under the Super Six format but knows he will have to put it on the line the next time he steps into the ring, as he had done unsuccessfully against Kessler.
