Sergio Perez has insisted that he will stay with Sauber for the rest of the season, despite constant speculation linking the driver with a move to Ferrari.

The 22-year-old, who became the first Mexican in 41 years to reach the podium after placing second at the Malaysian Grand Prix, has been touted as Felipe Massa's replacement.

"As a team they did a great job, and for me, my full commitment is with my team, with Sauber," said Perez.

"Obviously it's only rumours, but no, I will stay with Sauber for the whole season. It's only the second race and there's still a long way to go, so we have to keep improving, especially as we're a small team."

The next challenge of the season comes in China, with the Grand Prix due in two weeks' time.
