BBC Radio 5 Live
We have had great racing on the track, and in the pit lane. Fernando Alonso and Nico Hulkenberg collided at the pit exit.
Listen again to the BBC Radio 5 live commentary of the incident.
Lap 35/44
Massa has been bang in the middle of the action today and he goes up against Vettel into the chicane.
Vettel comes out on top and then targets Alonso - it's am easy pass and the German is up to sixth.

Nico Hulkenberg pitted quite a while ago, he has a few laps on his tyres, a medium tyre, and there will be 20 laps on his tyres by the time he gets to the end of the race, while Lewis Hamilton will only have 11 laps on his tyres.
Lap 34/44
"I'm not sure that's the right idea," Hamilton says on the radio after taking those medium tyres.
Mercedes tell him they think otherwise. They can see that Rosberg is clocking decent laps up front on his mediums.
Evidence immediately as Hamilton takes third place back off Hulkenberg.
Lap 33/44
Hamilton, now on medium tyres, relinquished one place to Hulkenberg, so he's in fourth. He managed to emerge ahead of Perez.
Lap 33/44
Hamilton pits. Much quicker than the last one.
Lap 32/44
Sergio Perez, somewhere, has gone past Fernando Alonso - we've yet to see how that happened. Perez is having a remarkably good day.

Lap 32/44
Red Bull are back on the radio and Ricciardo is told he is doing a "good job" at managing the the temperatures.
Lap 31/44
Ricciardo is told by Red Bull his left rear tyre is getting a bit warm. He'll have to manage that.
He's keeping Hamilton out of DRS distance though so is safe for now.
Lap 30/44
Boy oh boy, If you went to Spa today, you're getting your money's worth.
Lap 30/44
Perez grinds out an overtake on Massa, it's a lovely move, wheel to wheel. Massa gives just enough room and it's superb racing all round.
Perez up to P6.

Lewis Hamilton stopped on lap 22 so will have to stop again. It is guaranteed.
Lap 29/44
Top five: Rosberg, Ricciardo, Hamilton. Hulkenberg, Alonso.
All of them on medium tyres, apart from Hamilton, who has some softies.
Lap 28/44
Verstappen is overtaken by Bottas and remarkably comes nowhere near touching the Williams.
Ah, Verstappen was going ti pit anyway, so he dialled down the defensive aggression.
Lap 28/44
Ricciardo was able to come back out still in second - which gives you an idea of the gap he had on Hamilton.
Leader Rosberg has an almost 10-second advantage on Ricciardo.
