WBC super middleweight champion Carl Froch has slammed Joe Calzaghe after Calzaghe announced his retirement from professional boxing. Speaking to Setanta Sports News, Froch said it was “a shame he’s not had a career defining fight…he’s got a good record but I’m not going to lose my mind and say ‘he’s Sugar Ray Leonard’ because he’s not. I said a few weeks ago that he should retire. He got put on his arse by 43-year-old and 40-year-old in his last two fights. I’m not stupid. Joe Calzaghe has been a great champion. He’s a warrior, he’s tough, he’s strong. He’s beaten everyone put in front of him. But, how old was Roy Jones Junior when he fought him? He was 40-years-old. Bernard Hopkins was 43. Roy Jones was at his best 15 years prior to when they fought.” Froch had unsuccessfully campaigned for years to fight Calzaghe during Joe’s long 168lb title reign.
