"Because Ricky has
had his problems with drugs
and gained an awful lot of weight people are concerned. But he's not a fool, he'll do things properly," said former featherweight world champion McGuigan.
"He will take his weight down slowly, have lots of time to get ready, probably have an exhibition in the gym, box with smaller gloves on to feel what it's like to be hit again.

"He won't come back in a half-hearted fashion, he will give it everything. If that's not good enough, so be it.
"I don't think any ex-boxers have the right to judge another fighter, it's Ricky's decision and a very personal decision.
"If he decides to come back, I'm 100% behind the guy. I'd rather he did it now than waited five years and then decided to come back."
However, McGuigan, who took 22 months off after losing his world title to American Steve Cruz in 1986, conceded it could be a long road back for Hatton.
"We'll never really know how sharp Ricky is until we see him in that ring again," said McGuigan, who won three fights after returning to the ring before losing his final bout to Britain's Jim McDonnell in 1989.
"I never said it out loud but it was when the lights went off at night that I asked myself the question: 'Is it still there or not?'
"Will Ricky have the same body punching ability, the same relentless aggression? Or will he be a different fighter?
"Ricky is a lovely, lovely man and he's been great for British boxing so it would be devastating for him and British boxing if he came back and was a pale comparison of his former years.
"But I don't think that's going to happen. I don't think he'd come back if he didn't think he could be almost as good as he used to be."
