Former Renault Formula 1 driver Romain Grosjean is targeting a return to the category or a top Le Mans seat.
The 24-year-old, who completed a part-season with Renault last year, currently leads the GT1 World Championship with Matech Ford GT teammate Thomas Mutsch.
He is still hoping to return to F1, but has not ruled out moving from GTs to prototypes in endurance racing.
"I'm thinking of LMP and single-seaters," Grosjean said. "I have an open mind. "Option number one is to find a seat in F1."
