This has been a scrappy weekend for Ferrari and particularly for Sebastian Vettel.
For Lewis Hamilton, he has been leading the way all weekend - showing a clean pair of heels to Ferrari and his team-mate.
The rest of the top 10 at the moment sees Esteban Ocon seventh, Fernando Alonso eighth, Sergio Perez ninth and Carlos Sainz 10th.

Lewis Hamilton is really bossing it this weekend. He's the man on provisional pole and four tenths of a second quicker than anyone else.
Still three minutes left for Vettel to nudge himself on to the front row.

Starting fourth on the grid is not where Sebastian Vettel wanted to go this weekend, but there we have it - the Ferraris do not have the pace of the Mercedes.
Very similar to Q2 at the moment. The two Mercedes, then the Ferraris, this time with Raikkonen holding the edge, then the two Red Bulls. Four minutes left.

That's provisional pole position for Hamilton by quite a considerable margin!

It's very impressive that both Force India drivers managed to get into the final part of qualifying, because it was looking like it might be a struggle - Sergio Perez produced a fantastic lap.
They do push each other along and it's been a very consistent performance all season.
Sebastian Vettel is third behind the Mercedes pair of Lewis Hamilton and Valtteri Bottas with just over six minutes left.
But then Kimi Raikkonen jumps up to third, to push Vettel down to fourth.
Once again, Lewis Hamilton breaks the track record. That is the fourth time in two days. He goes round in 1:33.108, which is surely going to be good enough for pole.
So, who is going to get the pole position? Let's find out.

Adeel Ejaz: Alonso, again, driving the wheels off that McLaren! Insane ability to out drive that dog of a car!

Haas wanted to come here and impress, excite the Americans and get more money - they really need some help if they are to make something work tomorrow.

It's a very impressive performance from Carlos Sainz, within the Red Bull camp he got a little bit overlooked and it's sometimes been difficult to tell just how good he is.
On the basis of this weekend, he has settled in just perfectly and I think there will be smiles all around the Renault garage.
Once more, Hamilton is the fastest, this time by a margin of 0.332 seconds over Valtteri Bottas in a Mercedes one-two.
The two Ferraris are next, with Kimi Raikkonen ahead of Sebastian Vettel. Red Bull are fifth (Daniel Ricciardo) and sixth (Max Verstappen), with Sergio Perez, Carlos Sainz, Fernando Alonso and Esteban Ocon making up the rest of the top 10.

We were wondering who was going to be disappointed and the answer to that is the Williams team and Felipe Massa, because he was looking in really good shape earlier on but just didn't pull that lap together.
