Perez pulled off a major shock at the last grand prix in Malaysia when he raced to a runner-up result in the tricky wet conditions.

And although his P2 was a massive high for the 22-year-old Mexican and his team, it is back to work as they tackle the Shanghai International circuit for round three of the Championship.

"I am very much looking forward to the Chinese Grand Prix," said Perez.

"I'm very much focused on thinking about further improvements and continued with my training programme.

"We all have to keep our heads down and work hard. Our car can be competitive and we have to make the most of it."

Perez reckons the team could do very well at the Chinese race as the characteristics of the circuit should suit Sauber's C31.

"The high speed corners of the track should suit our car," he added.

"I especially like Turn One - it is a long and pretty difficult bend. The long straight will not be the easiest part for us, but, again, we have to maximise our potential."
