Timo Glock is set to leave Marussia after three years with the team.
German outlet Sport Bild claims that Glock will depart the Banbury based team.
"I have experienced three great years with Marussia. We part in friendship," Glock is reported to have told Sport Bild.
"I want new challenges [for myself] and continue my journey in motorsport."
It is indicated that an official announcement will be given on Monday.
Sport Bild also reports that DTM is a likely destination for the German, with Glock having been BMW Sauber's test driver in 2007. A Tweet from BMW factory driver Dirk Muller alluded to a potential move to DTM for Glock.
Glock joined F1 with Jordan in 2004, scoring points on his début in Canada. After winning the GP2 crown in 2007, he joined Toyota and claimed three podiums, with a best finish of second place in the 2008 Hungarian Grand Prix and 2009 Singapore Grand Prix.
Toyota pulled out of F1 at the end of 2009 and Glock sought refuge with Virgin Racing, which morphed into Marussia at the start of 2012, but in three seasons the team has so far failed to score a championship point.
