Pascal Wehrlein is considering a return to DTM with Mercedes in 2018 after Sauber opted not to renew his contract, according to reports.
Autosport believe both he and former F3 champion Dani Juncadella, who has tested for Williams and Force India in the past, are the main contenders for the role but there is a possibility that Wehrlein could look to secure a third driver role in Formula 1 instead.
Wehrlein finds himself without a seat in Formula 1 next season as Sauber decided to keep Marcus Ericsson and pair him up with Ferrari's rising star Charles Leclerc.
Wehrlein does remain in a partnership with Mercedes, but the Silver Arrows were not prepared to give him the chance to partner Lewis Hamilton as the German is still not the finished article.
He also does not appear to be in contention for the final vacant seat at Williams, who look to set to choose between Sergey Sirotkin, Daniil Kvyat and Robert Kubica in January.
If Wehrlein was to return to DTM with Mercedes, he would find himself in a similiar situation as he is now because the Silver Arrows are leaving the sport altogether at the end of the 2018 season in preparation for their move into Formula E.
Wehrlein spent three years in DTM before making the step up to Formula 1 with Manor Racing, winning the title with Mercedes in 2015.
