Leimer prepared to buy a Marussia Friday driver role

(GMM) The reigning GP2 champion is moving to put his formula one ambitions back on track.

Even with a reported $14 million sponsor offering to Sauber, Swiss Fabio Leimer could not find a debut race seat in 2014, causing him to turn away from F1 and move to sports car racing.

However, still backed by his wealthy and long-time sponsor Rainer Gantenbein, the 25-year-old is now eyeing a new route back to the grand prix paddock.

Roger Benoit, the well-connected veteran correspondent for Blick newspaper, said Marussia's door may be opening to Leimer.

Reporting from Barcelona, Benoit said Leimer could become Marussia's reserve and Friday practice driver this year, and "for a relatively small amount of money".
