Jul.18 (GMM/Inautonews.com) Marussia is yet to decide whether or not to keep French rookie Charles Pic on board for 2013.

Since the team’s inception as Virgin in 2010, Timo Glock’s teammate has been constantly changing.

In 2010 the German was paired with Lucas di Grassi, last year it was Jerome d’Ambrosio, and this year the second cockpit is occupied by 22-year-old Pic.

Pic told Ria Novosti news agency: “I think I have to stay focused on this year and make a good job, and if I do a good job it (a new contract) will come naturally for next year.”

Team chief executive Andy Webb admitted a decision has not been taken.

“Usually those decisions are made at the end of the season.

“We are constantly studying the situation with the drivers, but I will say that we are happy with Charles Pic,” he is quoted by the Russian website Championat.
