Lucas di Grassi has confirmed reports linking him with a seat with the new Manor/Virgin team next year, but says staying at Renault is also a possibility.
GP2 regular di Grassi, 25, completed the 2009 season as the reserve driver for Renault, who have so far signed only Robert Kubica for 2010.
"I am waiting for Renault before I know which team I will race for," the Brazilian, who at the weekend won the Granja Viana kart race with Felipe Massa, is quoted as saying by the Globo website.
Having driven Renault's R29 at the young driver test at Jerez last week, he added: "The priority if they continue is Renault, but if not for sure I prefer Manor."
Quoted by France's Auto Hebdo, di Grassi continued: "I think Manor, or now Virgin, is the best of the new teams. But most important is to find an available seat.
"If this is not with Renault or Virgin then (it will be) somewhere else. I'm speaking with several teams," he added.
