Nico Hulkenberg will definitely make his formula one debut with the Williams team in 2010, the German newspaper Bild-Zeitung reports.
The newspaper said Sir Frank Williams has taken up an option on the 22-year-old newly-crowned GP2 champion's existing contract, which this year saw him act as the British team's reserve and test driver.
"I cannot confirm that," Hulkenberg's manager Willi Weber said. "But I will be pleased if that is what happens."
Bild said Hulkenberg has been signed to replace his German compatriot Nico Rosberg.
