Jenson Button on Twitter: Kimi is the man to watch, looking after his tyres well.
Massa updatepublished at 16:23 British Summer Time 19 April 2015
Felipe Massa is coming up nicely through the field after his formation-lap bother.
He's just passed Felipe Nasr's Sauber for 14th.
That Williams is comfortably the third quickest car so Massa should be worth watching as he comes through the pack.
Ferraris in close companypublished at 16:22 British Summer Time 19 April 2015
Kimi Raikkonen is keeping Sebastian Vettel more than honest here.
The Finn could well get the jump on the four-time champ in the pit stops.

Job donepublished at 16:18 British Summer Time 19 April 2015
Rosberg is up to second but my word Vettel did not make it easy for him.
They both braked incredibly late for turn one but the Mercedes man had the inside line.
Good pass. He came from a long way back to get that done.
Mercedes from Mercedes, Ferrari from Ferrari.

Rosberg gunning for secondpublished at 16:16 British Summer Time 19 April 2015
Lap eight and Rosberg is getting racy.
He's just had a real lunge at Vettel but the Ferrari man shuts the door.
At this rate, and with DRS, it's only a matter of time surely.

Great stuff from Nico Rosberg. He sweeps past Rakkionen into the first turn at the start of lap four and he's back into third.
