Mercedes protege Pascal Wehrlein is to drive for Manor in the 2016 Formula 1 season,Autosport understands.

Reigning DTM champion Wehrlein has been linked with Manor for a number of months, but it is believed a deal has finally been struck that will bring the 21-year-old Mercedes reserve into F1, with confirmation of the move due shortly.

The young German is highly rated and already has a proven pedigree, winning the 2011 ADAC Formel Masters before finishing runner-up the following year in the Formula 3 Euro Series and fourth in the parallel European F3 championship.

In 2013 Wehrlein moved onto the DTM, becoming the youngest champion in the history of the series last year.

Since September 2014 Wehrlein has combined his DTM role with that of understudy to Lewis Hamilton and Nico Rosberg at Mercedes.

Now Wehrlein will get his opportunity to compete against the duo in a revamped Manor team, with its cars this year powered by Mercedes, and with a Williams transmission.

The second seat remains up for grabs. Established Manor drivers Will Stevens, Alexander Rossi and GP2 race winner Rio Haryanto are all vying to now become Wehrlein’s team-mate.
