Lewis Hamilton subsequently nips in ahead of his team-mate, doing a 1:20.802. That's less than tenth quicker than Valtteri Bottas. Nothing between them.

Kimi Raikkonen is fastest of all through the first and final sector but was a couple of 10th down on Sebastian Vettel in the middle sector. He does enough to go P1, though, with 1:21.112, a tenth quicker than his Ferrari team-mate.
Everyone else is back in the pits as the time to bolt on the softs arrives.
Sebastian Vettel is the first out on the quicker compound and does a 1:21.220.

He's currently fifth quickest, 1.4 seconds down on pacesetter Kimi Raikkonen.
