Jenson Button said he was “massively disappointed” to miss out on the top ten in qualifying in Spa.
Button qualified 13th after being knocked out in Q2.
Speaking afterwards he said: “I obviously did my first lap and then I cooled the tyres, not knowing that I didn’t have any more laps left.
“Obviously the track’s getting drier and drier every lap. I think I was second quickest or third quickest when I did my lap and didn’t get the opportunity to do another lap.
“So – wow – that massively disappointing and a big shock, because obviously in Q1 I was a second quicker than anyone. A misunderstand and a mistake on out part.”
Team mate Lewis Hamilton qualified and went past Button during the lap that got him into Q3:
“That was my cool-down lap,” said Button, “I didn’t realise that was it, obviously I would have kept pushing.”
Button added he has a “completely dry set-up” for tomorrow’s race, for which no rain is forecast.
