Lewis Hamilton delighted with United States Grand Prix triumph

Lewis Hamilton has described Sunday's victory at the United States Grand Prix as his 'best race of the year'.

The McLaren driver finished ahead of Red Bull's Sebastian Vettel following a sustained attack on the championship leader at the Circuit of the Americas in Texas.

"I'm so happy. The fans were amazing, thank you," said Hamilton. "It was such a warm welcome and one of the best, if not the best, race of the year - especially for me and the team. It's been a long time since we had a win. I'm so proud of the team and grateful for the support we've had."

Hamilton's teammate Jenson Button ended the race in fifth place.
