McLaren driver Fernando Alonso described his performance in the United States Grand Prix as one of the best of his career, despite failing to score a point.
Alonso was cut adrift of the pack following a first lap collision with Felipe Massa but hauled himself back up to fifth, before a suspected sensor problem caused a loss of power.
That dropped Alonso down the order and he was demoted to 11th position on the final lap.
"This was one of the best races of my career," said Alonso.
"To be running one minute behind the penultimate car on lap two, and then be running as high as fifth position with 10 laps remaining was quite a feat.
"After such a strong recovery, it was a shame that a mechanical issue in the closing laps put us out of the fight. That meant my feelings after the race were more sad than happy – but we can go away and continue to try to improve these issues."
Jenson Button described McLaren's 'perfect' strategy as he claimed sixth but conceded that further work is required.
"This was a strategic race – and, strategy-wise, we did a perfect race," he said.
"The team should be very happy with what we achieved; we made all the right calls, but still we need to go away and look at our lack of performance.
"In the opening laps, I really enjoyed racing in the drying conditions, and I felt like I was able to make a bit of a difference.
"We got onto slicks before the others, and made the right calls, but, once it was dry and everybody knew where to brake, it became a lot more difficult for us. We just couldn’t match the others’ pace once they all found their feet."
