With the future of the German GP as yet undecided, Nico Rosberg has admitted he fears for the future of his home grand prix.
Sharing the grand prix between Germany's two circuits, the Nurburgring was scheduled to host this year's event.
However, due to financial issues and a change of ownership at the circuit, there is no deal in place.
As such, there was talk of the German GP returning to Hockenheim this season but again a contract has yet to be secured.
And without one in place, Rosberg fears Formula 1 may not be visiting his home country this season.
"For as long as I can think there was a German GP and it was legendary, like the British GP – such a fundamental part of the F1 season," the Mercedes driver told Autosport.
"So it makes me feel very disappointed that it has not been fixed yet into the calendar."
He added: "There are so many motor racing fans in Germany, and Germany also has such a large representation in the sport with me, Sebastian and the other Germans and Mercedes.
"A big part of F1 is German, so I hope it works out."
