Mercedes:, external Unbelievably calm and detailed feedback from Nico Rosberg - his campaign is on the line and he's still right on it! What a fighter!

Super battle between Fernando Alonso and Jenson Button, with the two former world champions squabbling over 10th place. Button bravely defends through a sequence of corners, but he's forced into a mistake under pressure allowing Alonso to take the position.

Tom Beck:, external As much as I want compatriot Lewis to win WC, I don't want to see technical issues affect Nico's chances.

Colin White:, external Shame it looks like a race where a mechanical breakdown or pit stops will make whats happening on the track exciting.

Nico Rosberg: "It feels like more than the ERS. I'm literally holding back. Please investigate now please. It's more than the ERS."

Nico Rosberg tells his engineer that it's not just ERS that is not working. "Can you investigate that now, please? And then tell me what to do."

Moments later, Felipe Massa passes Rosberg to take second. There was nothing the German could do.
