Mark Webber believes he could have won the Malaysian Grand Prix had heavy rain started to fall a few moments earlier.
The Australian was one of several drivers who pitted for intermediates once it became apparent that the track was not wet enough for the extreme rain tires.
Just seconds after the drivers pitted, the skies opened and the extremes were again the right option.
Only BMW's Nick Heidfeld avoided the extra stop, while Webber had to return to put extremes back on, losing all his chances of a good result.
The Red Bull driver had been fighting for the lead earlier and he felt he had a shot at winning.
"That cost us the win, that's what they told me," Webber told AUTOSPORT. "I didn't really know. In the car you don't see anything and I didn't have a clue what position I was in."
Webber also backed the decision to not restart the race, as he reckons it was impossible to continue driving.
"There was no way to restart. The monsoon tires cut the water a bit but behind the safety car you just lose so much temperature that it's a vicious circle. You can't drive an F1 car in that.
"It was getting too dark, the track was waterlogged and I was just asking the others what they felt. They (the drivers) said it's impossible, they're dreaming, we can't race."
