Button goes into the European Grand Prix with 70 points, 19 ahead of closest rival and renault driver Mark Webber.
Elsewhere Lewis Hamilton has revealed he is still buzzing following his win in Hunary 4 weeks ago:
"It's great to be getting back to business after the four-week break. I'm still buzzing from the win in Hungary and I'm hopeful of being able to carry that pace into the Valencia weekend - particularly with our new upgrades to the car. It's a very demanding circuit, the kind of place that punishes any mistakes hard. It's quite tight and relatively slow, so it should suit our package. It's also very difficult to overtake, as we discovered last year - but, with our KERS, Mercedes-Benz has proved that anything can happen and I'm once again hoping that it will provide the difference in the race."
