Jenson Button is expecting rival teams to put up a tough fight from now on following his two consecutive victories in Australia and Malaysia.
The Brawn GP driver has started from pole position and won both races as his team has enjoyed a dream start to the season following its problems during the winter.
But despite his dominance in the early part of the year, Button is aware that the opposition will catch up and make his life more difficult.
"After the excitement of the first two races, it has been great to have the chance to relax and reflect for a few days since the dramatic race in Malaysia," said Button ahead of this weekend's Chinese Grand Prix.
"I am understandably delighted with how our season has begun. However we are only two races in and everyone at the team is aware that our competitors will not stand still. We fully expect a tough fight from here if we want to continue our early successes.
"Looking ahead to next weekend, the Shanghai International Circuit is an enjoyable one for the drivers and a good technical challenge to find the right setup.
"I particularly enjoy the high-speed sections and the overtaking opportunities going into the tight right-hander at turn five and at the end of the back straight."
Ross Brawn says the team has worked on solving some issues it had in the first two races and he is hopeful they will be in good shape in Shanghai.
"While there have been no developments to the car, we have taken the opportunity to address a few small issues which arose over the first two races and we are in good shape for the next race in China," said Brawn. "We are expecting temperatures will be cooler and less humid this year with the race taking place six months earlier.
"Therefore as was the case in Malaysia, we will need to be prepared for the unexpected as rain has played its part in recent races at the Shanghai International Circuit."
