Sergio Perez has downplayed rumours of a pending move to Ferrari insisting he will stay with Sauber for the "whole" season.
With Felipe Massa's days at Ferrari reportedly numbered, Perez, a member of the Ferrari Young Driver Academy, is believed to the favourite to replace him.
Fuel was thrown on the fire in Malaysia on Sunday where, after finishing second to Fernando Alonso, Perez was spotted in conversation with Ferrari team boss Stefano Domenicali.
The Mexican driver, though, insists there was no talk of him leaving Sauber for Ferrari.
"I only congratulated him," Perez said. "As a team, they did a great job."
He added: "For me, my full commitment is with my team, with Sauber F1.
"It's only the second race of the season and there's still a long way to go, so we have to keep improving, especially because we are a small team.
"For us, it's about getting closer to development, the others can improve more so it's important we remain focused.
"Obviously it's only rumours but no, I will stay with Sauber for the whole season."
