Welcome to our LIVE coverage of the second free practice session for the Italian Grand Prix at Monza.

Thanks for joining us - we'll be back tomorrow with coverage of FP3 at 10am UK time, and then qualifying at 1pm. See you then!

That's it from us - from the looks of things, this race could be staggeringly close on Sunday as most of the drivers are very, very close on times. Pole position and race tyre wear will be absolutely critical come race day.

The session comes to a close as Felipe Massa and Kimi Raikkonen all post laps of around 1:29 as they take the chequered flag.

Michael Schumacher is on a smooth-looking lap on his final run - looks like he's finally got his brake balance sorted as he laps with a 1:29.5, very decent with a heavy fuel load.

Cars going off all over the place: Michael Schumacher, Lewis Hamilton and Sebastian Vettel all run through chicanes. We've seen an extraordinary amount of that today.

Jerome D'Ambrosio, filling in for Romain Grosjean, is looking very solid, as is his team-mate for the weekend Kimi Raikkonen.

Most drivers are not using DRS right now, incidentally.

Looks like there will be no improvement in the times for the rest of this session - all the drivers appear to be on heavy fuel loads, lapping around the 1:30 mark.

Assuming that they're both running on high fuel loads, Hamilton and Rosberg look like the fastest men on the track right now.

Hamilton has just locked his brakes into the first chicane, then Vettel does the same on the entrance to Roggia. With tyres getting worn as teams look to race performance.

Every driver now out on the circuit - apart from Alonso, who is presumably off tearing strips off some of his mechanics.

Button's heavy fuel runs this morning were a second or so quicker than Vettel - still finding it hard to understand why Red Bull haven't bothered having at least a lap or two in something closer to qualifying trim to confirm their speed is competitive.

The Red Bulls are both back out on the track - Vettel's first flying lap here is a slow one, clearly on high fuel, and he's just over 1:30.

Confirmation here that Ferrari have suffered a gearbox failure. There's a possibility that they will have to take a five-place grid penalty if it cannot be patched up.

Felipe Massa is having tech trouble too: the vent on top of his helmet has just flown off on the straight.

Most of the cars back in the pits now preparing for the final stint. The two Red Bulls are 11th (Webber) and 13th (Vettel), will they be able to show some speed before qualifying?

Lots of work for Ferrari to do between now and qualifying. Alonso is quick, still sitting third, but will his car last the distance at his team's home race?

Alonso is taking his racing overalls off now - his session is over!

The mechanics are trying to restart Alonso's car after taking a look - and it won't start! Alonso is taking off his steering wheel, getting out and taking his helmet off.

Alonso comes into the pits, and drives straight up to be pushed back into the garage. Whatever next? Will his CD player start jumping? Will the cup holders break?
