DUSSELDORF, October 9 (Bundesliga) - Germany national team general manager Oliver Bierhoff fears the Bundesliga is in danger of losing several important sources of income due to the instability of the global economy.
With stock markets volatile, Bierhoff expects the Bundesliga to suffer a backlash.
"When you go into a recession, and I am assuming we are probably in one, then football will also be affected," he said on Thursday.
"Clubs still need people to go to the stadia and buy tickets, other consumables and pay to see games on pay-TV, and if that slows down, then it gets harder.
"It may also put some big companies off who may have been considering investing in football, but will put those thoughts on ice now."
The Bundesliga is already in a precarious financial situation after a deal for the sale of television rights from next season collapsed.
The German Office of Fair Trading ruled the deal between the German Football League (DFL) and broadcaster Sirius, which would have guaranteed 500 million euros per annum, was not in the public interest.
The DFL is now looking to sell the rights itself but does not expect to obtain anywhere near as much.
The current rights-holder pays a total of 420 million per annum.
