Sir Clive Woodward accepts he will have to leave Southampton to fulfil his dream of managing a football club.
The 50-year-old, who led England to rugby union World Cup success in 2003, realises a long reign for George Burley could force him out of St Mary's.
Woodward said: "I'm confident George is going to be here for a long time, and the club needs that sort of stability.
"I do want to manage a football club, but if George is successful that means I won't get the chance here."
Woodward, speaking at the launch of Southampton's new £1.25m Dome training facility which he set up, admitted his current role at St Mary's is frustrating.
He said: "At the moment I'm more of an administrator, which doesn't sit well on my shoulders.
"I would prefer being in charge of a team, but I'm not after George's job.
"I helped bring him here, and he is the boss. He buys the players and picks the team. That's something I hope to be doing one day, although I might have to drop down a couple of divisions to do it."
Woodward also called for unity in the Saints board room and accepts a new regime could oust him.
The Saints director of football last week launched a blistering attack on major new shareholder Leon Crouch, who said he would work towards Woodward's removal if he gains a seat on the board.
Woodward said: "To be successful you need everyone pulling in the same direction.
"You can't legislate for what other people might do and if I left now, I would be happy with what I have done at this club.
"If you worry about people saying things like that, you'd never get anything done. These things happen and you have to take it in your stride.
"I'm not going to back off if things are said about me by people like that.
"But as long as I'm onside with George Burley, that's all that matters."
