The former Red Devils defender has been linked to a possible director of football or sporting director role.
Ferdinand, who is based in London these days, has admitted there is some interest on his part in such a position.
But the ex-England international would not be drawn any further on the speculation.
"It all depends on the shape of the job," he said to FourFourTwo when asked about returning to United someday.
"I don't think it's all been outlined at Man United in terms of – that's the job and this is the description. I think there's a lot to talk about within that.
"To be fair to Man United in that kind of role, the responsibility that comes with that, you can't lie and say that that's not a turn-on.
"Because you are helping to shape the fortunes of a club of that stature. That's a huge job.
"All the boxes would have to be ticked that you're got in your head before considering something like that.
"I think decisions made at a football club – not all, (but) some of them should come with a football thought process in the background somewhere, (someone) that understands that side of it and can make that kind of decision."
