The boss of Hockenheim has warned that Formula 1 could "bleed out" if too many traditional races are axed.
It is believed the German and Spanish grands prix will be the two that are axed to make way for Zandvoort and Vietnam in 2020.
Georg Seiler, boss of the Hockenheimring, admitted: "If only the fee decides, then it looks relatively bad for us.
"Actually we only have a chance if another grand prix fails and the German grand prix is explicitly desired by Liberty."
It is notable that other traditional F1 races, including Silverstone and Monza, had also been in doubt as Liberty fields offers from rival promoters.
Seiler thinks traditional races need better protection.
"I would only wish that we take on a different or special role as a traditional race," he told Suddeutsche Zeitung.
"This sport could bleed out if there are fewer or even no traditional circuits. Racing with empty stands in countries with no motor sport tradition whatsoever must not be the goal of the owners of this series," Seiler added.
