The designer of India's new Buddh circuit insists the venue will be ready for its inaugural race late this month.
Hermann Tilke was talking to Germany's Auto Motor und Sport after the latest round of speculation about the last stages of construction near Delhi.
Asked if the F1 paddock and spectators need to be worried three weeks before they arrive at Buddh, he said: "No, everything with the planning is on time.
"This is actually as it always is -- almost all of the new tracks are finished just in time. It will also be the case in India."
Tilke admitted however that the entire facility may not be complete.
Certain parts of the infrastructure will still have something to do
"It is safe to assume that certain parts of the infrastructure will still have something to do. But that's true of almost everywhere as well.
"I am very satisfied and I think the results speak for themselves," he added.
