Amir Khan has reopened a feud with Carl Froch by claiming the world super-middleweight champion should retire after his controversial win over George Groves.

Khan, the former two-time world light-welterweight champion, said he thought Groves would have beaten Froch if the referee had not stopped the fight.

Groves has called for a rematch, but Khan feels Froch is too old. “He’s past his best, past his sell-by date,” Khan said. “Froch should retire. He’s on top at the moment with the belts, I think in his next fight he’ll lose those belts. He got a very close win against Groves because he was losing almost every round. He was losing the fight.”

This is not the first time Khan and Froch have clashed. After Khan was beaten by Danny Garcia last year, Froch said if it had been him, he would have retired.

Nathan Cleverly’s cruiserweight debut on Saturday has been cancelled after he was forced to withdraw from his meeting with Daniel Ammann due to a back injury.
