Robert Kubica is one of the most highly-rated Formula 1 drivers
In-form Renault driver Robert Kubica has refused to commit himself to the team for next season.
The 25-year-old Pole is sixth in the drivers' standings and has two podium finishes in seven races this season.
That form has seen him linked with a move to Ferrari and when asked about next season, he was non-committal.
"It's not the time to talk about it," he said. "There will be time for me to talk about whether I will be staying with Renault or not."
He added: "For me, for now, it is still too early. It's all about feeling, and once I get a feeling as to what I must decide then I will do it.
"Too many people, when I signed for Renault, told me I was wrong, that it was a bad move.
"But I'm pretty happy with my decision and I hope I can rely on my decision-making for the future."
Kubica joined Renault on a one-year contract in the close-season following three years with BMW Sauber.
His future appeared in doubt in December when the team was taken over by Luxembourg investment company Genii Capital, but he opted to stay after talks with the new owners.
In a superb debut season, he has only once been out of the top 10 and finished on the podium in Australia and Monaco.
He is 26 points behind championship leader Mark Webber, and 61 points ahead of his rookie team-mate Vitaly Petrov, after seven of 19 races.
"We can be happy with the start to the season and the job we are doing," added Kubica.
"The guys in the factory are also doing a good job because for every race they are delivering new bits on the car.
"It's not easy to catch up with the other teams because they are working hard too, but it's good to see the people pushing with the way they are working on the car."
