Jenson Button insists the pressure is on those behind him in the title race rather than himself as the race for the world title continues at the Singapore GP.
The Brawn GP driver holds a 14-point lead over team-mate Rubens Barrichello and the pair showed good pace in the first session of free practice on Friday to sit at the top of the timesheet.
Sebastian Vettel and Mark Webber, who are third and fourth in the Drivers' Championship respectively, suggested they too could be on form come with promising displays in the second session of practice.
But Button believes the onus is on the Red Bulls, and particularly Vettel, to produce a good performance this weekend.
"He (Vettel) is 26 points behind and he obviously has to beat me and by quite a bit this weekend," said the 29-year-old.
"Their car looks pretty quick around here, I'm not sure if it is as quick as ours but we will have to wait and see for qualifying and see the race pace.
"It is a very important weekend for them but, for us, we want to do as well as we can and we are not under pressure."
