The Ulsterman took over from Giovanni Trapattoni in November last year, calling upon Keane to assist him.
But it seems the partnership could be short-lived as O'Neill has said Keane has held informal talks with Celtic over the vacant manager's job left by Neil Lennon.
He confirmed that Hoops majority shareholder Dermot Desmond had been in touch with him to arrange a discussion with 42-year-old Keane.
The 62-year-old has said he would be disappointed to see the former Republic skipper go, but added that such an offer "might not come around too often".
"I only reiterate what I said right at the beginning, which I think has been enhanced over this last period of time," O'Neill commented.
"Roy has been, selfishly, he's been great for me. I've genuinely enjoyed working with him.
"He's sometimes a totally different character to the one that you see on the TV. He's been excellent, the players have enjoyed him immensely.
"I can only say that naturally I'd be disappointed if he left because I really think that he's been terrific.
"We have only had four games with the squad, but he's been excellent and I don't think that he'd give that up lightly."
Celtic confirmed they are in discussion with "a number of excellent candidates", with former striker Henrik Larsson and Owen Coyle also in lined up as favourites for the role.
