Sergio Perez says he expects more progress from McLaren in this weekend's Chinese Grand Prix as the Woking-based team seeks to rebound from a tough start to the 2013 season.

Both Perez and team-mate Jenson Button were off the pace in Australia during the opening race of the campaign and have managed just four points between them so far - with Perez's ninth place finish at Sepang matching Button's similar result in Melbourne.

There were signs of progress however in Malaysia last time out and Perez said he was hopeful of more progress in Shanghai as the team works towards the introduction of a major upgrade for the MP4-28 when F1 heads back to Europe for the Spanish Grand Prix next month.

"We are positive," the Mexican said of the weekend ahead. "We expect to do progress every single race. I think we can make here make a little bit of progress but the most important is that we can learn a lot this week about the car which will help us for the big update that we are having for Europe. Once we go back to Europe."

The issues McLaren has faced means Perez has so far been able to replicate the kind of results he enjoyed with Sauber last year but he said it hadn't relieved any of the pressure he has put on himself to succeed.

"I think the pressure is always there," he said. "It doesn't matter in which team you are, you have to deliver results. I want to deliver, I want to take the maximum out of the car and I know that the car will come back and we will be competitive quite soon, so I am confident in that respect.

"About the pressure, there will be always pressure when you drive for McLaren. Even if you are at the back of the grid you have the pressure to deliver and to try to make the most out of the car that you have."
