@MathewGeorge: Alonso won't be staying at Ferrari, even if they have a third car next year. That's as close to a guarantee as I can give you about 2015.
@HueMercsFanfromMalta: Nice to imagine, but team's aren't going to splash out on three superstars because the third cars can't score any points - so it would be a complete waste of money. Third cars will be perfect to give young drivers an opportunity for race experience.
We have the Mercedes cars back out on track now, and they've been joined by Button. All a bit quiet out there early on.
@MathewGeorge: Nope, the third car will be a non-points scoring car, even if it finishes in the points.
@satyaban: Good spot, I stand corrected.
@Phil,Maidenhead: Nope, the third car is there solely to make up the numbers of the grid. Hence why it seems like a good opportunity for younger drivers.
@Siddhesh: Well, I doubt they would have signed Vettel without knowing there was a gap available. So that would suggest Alonso's contract has already been ended, which is true according to reports in Italy.
Button has jumped into P1 with a 1:43.245.
@NovaF1Racer: No, the designated third car can't score points, full stop.
Lots of activity out on track now, Nasr has gone P3 and Verstappen has just slotted in behind him on his first run. Impressive stuff from the Friday runners early on.
No-one knows for sure about the third cars, by the way - but as far as reports from reliable sources suggest, a third car would not be in a position to score any points. So it's not certain, but a possibility.
People in the know have said a designated third car can't score constructors' points, but drivers' points are a bit of a grey area. As many of you are saying, it would be rather hollow if someone wins a race in a third car and doesn't take the points. All a bit of a mess.
@Yevgeny: Luca di Montezemolo said Alonso is definitely leaving Ferrari last month.
Magnussen has slotted in behind his team-mate into second, with Ricciardo down in third. Alonso is out on a lap of his own but has run wide at the end of the long back straight.
Replays show Nasr running wide at Turn 13.
Alonso's first lap put him P6, behind Massa - but the Brazilian then leaps into fourth behind fellow countryman Nasr.
@HueMercsFanfromMalta: After Montezemolo told them!
@Yevgeny: I would say h
e's as close to a reliable source as there could be at Ferrari, even if he's no longer president.
Alonso has jumped into P2 now, 0.165s behind Button. Raikkonen up into fourth eight tenths off the top of the timing screens.
@phoenix: The fact Grosjean is still being cryptic about his future suggests there is still a chance of another drive for him further up the grid. Grosjean said earlier this year his Total backing wouldn't be a hindrance at a team like McLaren.
@MichaelBialocur: I can't see past Hamilton, especially if he wins here.
Magnussen has now jumped above Button into P1, setting a 1:41.078.
