The report said Dennis has until the end of this month to find new investors.
"Auto Bild has learned that the favoured candidate as partner and team boss is the former McLaren driver Gerhard Berger," wrote the German magazine.
Berger, a former Grand Prix driver and co-owner of the Toro Rosso F1 team, denied the whole thing.
"I have nothing on the table. The situation is the same as it was in May, when you [correspondents of the Auto Bild] last visited my office in Monaco,” Berger told the magazine afterwards.
Berger, who drove for McLaren when Honda was its engine supplier, added a very interesting detail however: “But if I had a specific proposal, which would have involved the automaker, I would have thought".
Asked for a comment on the claim, a McLaren spokesman said: "This is complete and utter nonsense."
