Like Perez, Kobayashi started the race on medium tyres. But he picked up damage on the first lap and had to pit for a new front wing:

“Everybody tried to stop so as not to run into the accident,” he said afterwards. “I touched the car which braked in front of me.

“Not only did my front wing come lose, but I also damaged a tyre and therefore I had to change to a set of used soft tyres.”

He retired on lap 22 when he lost power in all gears.

Perez shared row seven with his team mate but out-qualified Kobayashi – for the eighth time this year – by three tenths of a second.

He ran until lap 33 – well past half-distance – without changing his tyres. He was up to seventh place and had a good chance of keeping the position until his gearbox failed as well.

“We missed a great opportunity to score points today,” he said.
