"That was pretty close on that restart," the Mercedes engineer suggests...
"Close to what?" says Hamilton.
"Close to the safety car," the engineer ventures, bravely...

There is debris all over the circuit here so the safety car is out again. This will allow Valtteri Bottas to catch up with the back of the train...
Image source, Getty ImagesWe have ANOTHER safety car.
A chunky piece of bodywork from Raikkonen's car has come lose and race control was very quick to neutralise the race.
We're racing again and straight away the Force Indias mount a dual attack on the Ferraris.
Vettel just holds off Sergio Perez to keep second place, but behind the limping Raikkonen first fourth place to Williams' Felipe Massa and then fifth to Esteban Ocon.

Ferrari have told Kimi Raikkonen that his car is "heavily damaged" on the left side after the earlier tangle with Bottas but there is "nothing we can do".
And Bottas duly unlaps himself from the rest of the field.
A lifeline for the Finn. He'll drive round and tag on to the back of the train.
Lots of stops made after that safety car. Stroll stayed out for an extra lap in the Williams and he's come back out in seventh.

Verstappen has now retired from four out of the last six races...
He's not a happy bunny. He comes in, waves his hands in the air and takes his seatbelts off.
His team tell him to wait a moment but then break the news that the problem is terminal.
