Belgian grand prix boss Andre Maes doubts the Netherlands can quickly put together a Formula 1 project.
After 35 years promoting the iconic race at Spa-Francorchamps, promoter Maes is stepping down. Formule 1, a Dutch publication, said his replacement is not known.
Competition not a problem
But the Spa race's future is at least secure, after Maes inked a new three-year deal with Liberty Media earlier this year.
However, reports that promoters at former F1 circuit Zandvoort are in talks with Liberty could endanger nearby Spa's medium-term prospects on the calendar.
Maes says competition is not a problem.
"It is only natural that we constantly have to fight for our place," he said.
"We do not veto a race in the Netherlands, but we have asked if there are plans. If there is a Dutch grand prix, they will need at least three years to prepare everything."
