Formula One supremo Bernie Ecclestone is hopeful Sauber will survive their current financial crisis after admitting he cannot step in to bail them out.
The Swiss team are struggling to pay their suppliers, which in turn is threatening their prospects of seeing out the season.
Team owner Peter Sauber has described the position as "painful" and "embarrassing", and has refused to rule out the prospect of selling his marque for it to survive.
Ecclestone, however, will not be lending a helping hand as he said: "We have agreements that require us to treat all the teams equally."
With regard to the prospect of outside investment, speaking to Swiss broadcaster SRF, Ecclestone added: "They're a good team and I'm sure there is more than one possible buyer.
"I don't want to imagine F1 without Sauber. Ideally, they will find new sponsors in the long term.
"Even companies who are willing to support them in the short term would be fine. The team deserves to be helped."
