Promoter Frank Warren believes it would be a mistake for Ricky Hatton to make a return to the ring.
The former world champion has announced a press conference for Friday in which it is thought he will announce a surprise comeback after three years out.
But Warren, who guided Hatton to his first world title against Kostya Tszyu in 2005, hopes Hatton stays retired.
"I'd prefer Ricky not to box. He's not going to get any better at the age of 33, but it's his decision," the promoter said.
"He's returned to the gym and that has given him focus and direction, but I'd rather he stay there training and not fight.
"I hope he's still got it, but it won't be there...it just doesn't happen like that. He's had a lot of problems outside the ring for a long, long time and it just won't happen.
"I believe he's had a good career and he should reflect on that. No-one should be encouraging him to return and I just hope it doesn't wind up being a big disappointment for him."
Retirement ushered in the darkest period of Hatton's life and the Mancunian reached his lowest ebb in 2010 when he checked into rehab to be treated for depression.
"The writing was on the wall from his last fight that he should retire. Then he had his personal problems," Warren said.
"But the one thing he's done that we should give him credit for is clean up his act.
"When it came to fighting Mayweather and Pacquiao, it was a step too far for him, but then it is for virtually all fighters."
