Sources: Marcus Ericsson to drive for Sauber in 2015

Marcus Ericsson will not take part in the United States Grand Prix as Caterham continues to search for funding.

Marcus Ericsson is set be a Sauber driver next year, according to sources close to the Swiss team.

It appears that the Swede has beaten both Giedo van der Garde and Esteban Gutierrez to the seat alongside Adrian Sutil – assuming that the German’s ongoing contract is fulfilled.

Ericsson has shown well in recent races after weight saving and brake and aero updates at Caterham made him much more comfortable with the car.

He has substantial sponsorship from Sweden, and the suggestion is that an early payment would help to get Sauber through the winter.

Speaking to FOXSports.com, he said: "I’m not involved in these things but I know my management are working 100% on making me stay in F1. We’ve done this first year now and I’ve started to perform on a good level, and of course I want to stay and continue that. There are not many seats available and of course Sauber is one option, and it’s one of the teams we’re talking to."
