"Nyck could have been one for the future for Mercedes. They were right to let him go. But they might regret it, one day..."

"Hanging onto the rear end a bit... looks a little bit snappy, unstable on the rear."

A 1m32.969s puts the Aston Martin driver 0.483s off Sainz's best lap.

"The crucial thing for Mercedes is they've answered a very important question. Is this, essentially, a good car? Happily for Mercedes, the answer to that question is yes it is."

A 1:34.178 puts the Mercedes driver 1.6s behind Sainz.

How things currently stand...

A 1m33.490s from the Alpine driver sends him up to fourth.

Alpine were, on average, the slowest team yesterday.

"For now, we are really not focusing on [Red Bull] because we had very different programmes yesterday. 

"We are happy with what we have done, we have no idea how much fuel they have in the car and we have no idea how much they are pushing there.

"There are so many questions, so we don't focus on that, we focus on ourselves. We'll see what happens in the next few days."

Alfa Romeo driver shoots up to second, six tenths behind Sainz.

 Sainz, Alonso, Magnussen, Perez, Hamilton.

Good news.

Mercedes have fixed whatever broke off Hamilton's car and the seven-time world champion is back out on track now after a brief spell in the pits.

Lando Norris is out on track and finally sets his first lap time of the day to go sixth.

It looks as though McLaren have got on top of whatever they were working on a little earlier. 

Another improvement from Sergio Perez, who goes P2. 

It's two purple sectors from the Red Bull driver, but he ends up just 0.041s shy of early pacesetter Kevin Magnussen.
