Calzaghe (left) retired as an undefeated world champion
Joe Calzaghe says Ricky Hatton should ignore all the would-be advisers who have urged him to retire from boxing and make his own decision.
Hatton's future in the ring has been in doubt since his second-round defeat by Manny Pacquiao three weeks ago.
"If I was knocked out in the second round I'd want to keep fighting so I could finish with a win," he said.
"But I'm not going to tell Ricky what to do with his career. He needs to sit back and decide for himself."
Calzaghe added that Hatton "knows himself better than anyone else".
"I suppose he's going to do what he wants to do. At the end of my career, nobody told me what to do. I retired because I wanted to retire on my own terms," said the Welshman.
After extending his glittering career to 46 wins from 46 fights with a comprehensive points victory over the legendary Roy Jones Jr in November, Calzaghe took three months to decide on his future before eventually announcing his retirement.
The 37-year-old Welshman said he had nothing left to achieve in the sport and he bowed out as an undefeated super-middleweight and light-heavyweight world champion.
Hatton suffered a devastating defeat by Pacquiao in their IBO light-welterweight world title fight in front of 20,000 of the Mancunian's adoring fans in Las Vegas on 3 May - only his second loss in 47 fights.
The 30-year-old has since claimed he has no appetite to lace on a pair of gloves again, adding fuel to speculation that his 12-year professional career has come to an end.
If the Pacquiao fight does become Hatton's final appearance, Calzaghe still believes the Englishman is certain of his place among British boxing greats.
"Ricky Hatton has done very well; he's made an amazing amount of money and become a two-weight world champion," said Calzaghe.
"He's one of the best fighters we've seen from Britain. OK, he lost against a much better fighter - Manny Pacquiao is a great fighter, not just a good fighter. But that's what happens."
Calzaghe says he has absolutely no regrets about his decision to hang up his gloves and resist the lure of another potentially lucrative fight.
