Joe Calzaghe believes George Groves is capable of conquering Carl Froch if their British battle goes ahead.

Froch currently holds the WBA and IBF super-middleweight belts and is willing to face Groves if he becomes a mandatory challenger for one of his titles.

The Nottingham man had previously dismissed Groves and James DeGale as possible opponents, claiming he would ruin the unbeaten duo's careers if they met in the ring.

Calzaghe insists Froch should not berate his British rivals for calling him out and accused 'The Cobra' of acting in a similar manner when he reigned the division.

The Welshman accepts that Groves would be a big outsider against a seasoned champion like Froch, but feels he could spring an upset with the correct game plan.

"He would be the underdog I think, but yeah I think he has a chance," Calzaghe told Ringside Toe 2 Toe podcast.

"I think he has a chance of beating Froch if he fights the right tactics. Like I said, Froch can be outboxed. I think he's shown that. Whether he is good enough to outbox him I'm not too sure, but why can't he call him out. He's undefeated. Froch was in the same position, calling me out all them years ago.

"For him to ridicule these opponents is out of order a bit, considering that's what he did, chasing me for years and years when I was looking at bigger fishes to fry, so that's part of boxing."
