SAM Allardyce has dismissed the notion that either he or any other Premiership manager could take charge of England on a part-time basis.

Although rubbished by the Football Association yesterday, the revolutionary idea of "job share" arrangement is believed to have growing support in the corridors of power at Soho Square, and the Wanderers boss is one of the men whose name has been touted as a possible successor to Sven Goran Eriksson.

But Allardyce described the concept of a club-country dual role as "mentally too demanding" claiming it was only being discussed because the FA, massively in debt, was desperate to cut costs.

"You'd have to have one hell of a patient chairman to allow you to do it in the first place," he said.

"But as a manager of a Premiership football club, it doesn't matter whether you are doing good, bad or indifferent, you just can't walk out of a Premiership season into an international tournament of the highest quality.

"What manager is going to put himself through that and what wife is going to let him? Where does he get his holidays? Where does he get his time off? How does he stop himself getting burned out?

"And, if it went wrong, it would stink of unprofessionalism and the media would have a field day."

Despite Wanderers chairman, Phil Gartside, being a prominent member of the influential FA Board, Allardyce took a swipe at the governing body, for putting finance before football.

"The FA is now Bolton Wanderers," he said. "It's got massive debts and when that happens you look where you can cut corners. All of a sudden the finance becomes more important than the results, which is not what you expect with England.

"I've had five years in dealing with £38m and £40m of debt here ... I've no idea exactly what the FA's debt is or what

it's going to cost them to finish building Wembley, never mind what's going to happen to the development of the game, if there's no money.

"The FA Board has a massive responsibility to reschedule and restructure ... but first and foremost they've got to finish Wembley."

Such are the pressures of club management, Allardyce has re-affirmed his intention to retire in five years.

"The game has changed so much," he said, "and at that stage of your life it might be that you'll want to see your grandchildren a bit more and see the world a bit more. You want to enjoy that side of life before it passes you by and you're in a wooden box."

Allardyce, who will be 50 next month, has confirmed that he has opened negotiations with Gartside, over an improvement to his current 10-year contract, although both men insisted there was no rush.

"Sam's got a contract and it's still got five years to run," the Wanderers chairman said. "Yes, we will talk about changing it, but there's no big drama."

The sudden interest in Allardyce's contract has been sparked by the offer to manage Newcastle following the sacking of Sir Bobby Robson and recent speculation touting him as a target for Manchester City, should Kevin Keegan suffer a similar fate.

He said: "It is nice to know people are looking at what you are doing and thinking about you for their club.

"These talks have come about by someone else wanting you, which I feel is sometimes not the right way to get it. But you have to take the opportunity when it comes along.

"You would think they would come along and reward you without someone else coming in for you but football does not seem to work like that."
