Jordan admits he has seen revenue dip in some areas of his club recently but stressed winning teams would continue to prosper.

Jordan told BBC Radio Five Live: "The economics of football are always based upon success.

"There are people buying football clubs for a number of reasons: some people buy them because they can and they want to; some people buy them because it gives them credibility; some people buy them because they want to be associated with a good British asset; some people buy them as a very expensive life insurance policy.

"But there are many reasons why many wealthy people are pouring money into football clubs."

Jordan said that despite the money pumped into football, even at Coca-Cola Championship level which is where Palace currently are, clubs must fight to keep their supporters given many may have personal financial issues.

"You're going to find its a battle to maintain your fan-base and you're going to have to be realistic in your pricing," said Jordan.

"I think there may be a downturn now, with clubs having to look at being more inventive in how they attract fans.

"I notice there is a downturn in commercial sponsorship, people aren't spending money in corporate areas of the football club that they once were."

Football Association independent chairman Lord Triesman has warned that clubs could be vulnerable during the world economic crisis.

And former FA executive director David Davies believes Triesman's take on the health of the game may prove to be more accurate than Jordan's perception.

"I believe Lord Triesman will prove Simon wrong," said Davies.

"He (Triesman) is a shrewd guy.

"I believe he has a huge opportunity as independent chairman of the FA to address some of the key issues which have existed for many years."

Regarding ownership, Davies added: "The moment we get worried about these foreign owners, and we say 'We don't really want you', they may just take us at our word."
