Decision-time regarding Pascal Wehrlein’s F1 future is now imminent.
The new DTM champion’s employer, Mercedes, has been in talks with Manor about a race place for the 21-year-old.
But it is believed Will Stevens and Alexander Rossi’s backers have substantially more to offer the backmarker team than Mercedes’ EUR 4 million for a Wehrlein seat, according to Auto Motor und Sport.
Wehrlein said: "It will be decided for sure either this week or next week at the latest."
If the Manor seat is a no-go, the German youngster will simply stay in DTM.
"If formula one does not work out, it would be a very big challenge for me to try to defend the title with the HWA team," he said.
"I know how hard that would be."
