Max Verstappen, perhaps...

Going big there Andy.
Speaking of Fernando Alonso, how's he getting on so far today? He has the 10th fastest time at the moment with 1:27.110.
Meanwhile, Kimi Raikkonen fancies a bit of alone time on the track. He breaks the silence to head back out with softs on.

So far so good for Max Verstappen? Not quite. "I cannot accelerate," he says over the radio.

A little 360 for Felipe Massa as he spins in the Williams at Turn 5.
"All OK," he is asked.
"Yep," is the reply. No need to say much more than that I suppose.

BBC Radio 5 live pit-lane reporter"The car has stopped smoking. It is the right hand side of the rear and the cooling system is one of the things they have worked hard on at Force India. They have lots of upgrades this weekend and they said the cooling system is one of the things they wanted to check."

Esteban Ocon is told to box. Looks like he might have a puncture. There's also an issue for Sergio Perez as smoke plumes out of the rear of his Force India as he comes out of Turn 9. Straight into the pits he goes.
