Lewis Hamilton and Nico Rosberg are both back in after five laps on the soft tyres, nothing between them at all. Could we be in for a close battle between the two this weekend?
Meanwhile Daniel Ricciardo is out on the circuit after that hydraulics issue but Jenson Button's frustrating afternoon continues. He has managed just three laps so far in FP2.

Nico Rosberg, on the softs, is fastest of all through sectors one and two but is slower through the third sector and finds himself just short of Lewis Hamilton best lap, 0.021s slower.
With 45 minutes gone, Hamilton is fastest, ahead of Nico Rosberg, Sebastian Vettel and Nico Hulkenberg.

After Carlos Sainz beached his car this morning there's another Toro Rosso off the track as Max Verstappen spins into the gravel after losing his rear at Ascari. He manages to avoid the barrier and gets back onto the circuit.

Kimi Raikkonen's first soft-tyre run moves him above Nico Hulkenberg and into third. He is about a second faster than he was on the medium tyre.

A couple of drivers have made the switch to softs, Nico Hulkenberg among them and his first time on the new compound sees him up into third with a 1:25.720. That's half a second slower than Lewis Hamilton, who is yet to switch to the faster tyre...
