Absolutely magnificent attacking and defending driving from Daniel Ricciardo and Valtteri Bottas.
Brendon Hartley has dropped to last in his debut race.
Ricciardo dives past Valtteri Bottas at turn one of lap two, it is wonderful stuff, the pair are wheel-to-wheel through a few corners and Bottas just about forces his way back in front of the Australian.

Absolutely inch perfect start from Sebastian Vettel. The second that light went out he launched his car off the grid.
Force India's Esteban Ocon has also enjoyed a good start, moving into fifth past Kimi Raikkonen
What a start from Sebastian Vettel. He does exactly what he needs as he jumps past Lewis Hamilton off the start.

Lewis knows it is unlikely to happen [to win world title today]. He has been realistic about his prospects. He knows Vettel will have to hit trouble. The feeling is he is due a decent run today.
We've talked about it already, and here it is again - just how Lewis Hamilton can win the world title with this fancy graphic.

"Gentlemen, start your engines and let's get ready to rumbleeeeeeeee."
Not sure if that is spelt right. But that's what Michael Buffer has just screamed out. The fans love it.

Ferrari have been very good at coming from behind. There are things you can do in this Grand Prix to mix up your strategy.
We have focused on the drivers' championship, but the constructors' championship can also be decided today.
Mercedes have won the Constructors' Championship in the last three years and Ferrari are going to have to go some to deny them a fourth consecutive title.
If either Lewis Hamilton or Valtteri Bottas win today then the Constructors' Championship is Mercedes'.

Image source, Getty ImagesWhile Carlos Sainz starred in qualifying on his debut for Renault, New Zealander Brendon Hartley did a solid job on his F1 debut with Toro Rosso.
He said he was “pretty happy with how the weekend has gone so far” but the impression was that he was slightly disappointed to be 0.8secs off team-mate Daniil Kvyat in qualifying, and he said he had simply failed to get the peak performance out of the notoriously difficult Pirelli tyres.
But he said: “The long-run pace, I feel confident I can do a good job (in the race).” There has been no official decision on who will partner Frenchman Pierre Gasly over the remaining three races, but the sense is it will be Hartley, not Kvyat.

Lewis Hamilton's brother Nick has been speaking to BBC Radio 5 live: "He is super relaxed. It has been a good weekend so far. It is probably the most relaxed I have seen him this year which is really nice.
"I think Lewis is driving better than we have ever seen him. He will be tough to beat but in Motorsport anything can happen. I am not counting too many chickens yet."
