Kevin Keegan has played down suggestions he was approached by Newcastle to become director of football above Sam Allardyce at St James' Park.
He told the BBC's Inside Sport show: "It's absolutely impossible to give Sam a job at Newcastle and then go and fetch someone who's going to be some sort of threat, it doesn't work.
"Sam would be a fool to let it happen, the guy who goes in would be a fool to accept it and the chairman, who's not a fool, would be a fool to go and do it. It doesn't work."
Keegan also admitted he is not keen to return to management as he has barely watched a game of football since his troubled spell at Manchester City came to an end.
"My life's gone in a different direction," he added.
"I haven't watched a game of football live since my last game at City and I can't even remember what game that was now.
"So I don't think that'll happen but I do get offers to go back into football. But I made a decision that I would do something different."
