The 29-year-old has been fully focused on F1 since 2006, when he was a test driver with the Midland (now Force India) team.
He moved into the Silverstone based squad’s race seat the following season, but lost his place for 2012 as Nico Hulkenberg stepped up from the reserve role.
German Sutil has also run into legal trouble due to the Eric Lux assault affair, resulting in a criminal conviction for grievous bodily harm.
His best option to keep racing this year, therefore, could be an offer from a World Touring Car Championship team, German newspaper Bild reports.
Another offer on Sutil’s table is from an Indycar team, the report added.
“Our focus is on returning to formula one,” his manager Manfred Zimmermann commented.
