Jenson Button admits car was not quick enough in Korea

Jenson Button admits his fourth-place finish in the Korean GP was "not perfect" as he could not get close enough to the drivers in front of him to make an impression.

The McLaren drivers says the Yeongam circuit is not his favourite and that fourth was the best he could have achieved.

Sebastain Vettel won the race, Button's team-mate Lewis Hamilton was second and Mark Webber third as Red Bull wrapped up the construtors' title.
