Welcome to coverage of second practice for the Italian Grand Prix at Monza.

But it is the German title hopeful nevertheless that tops afternoon practice at Monza.

On his final effort Vettel tuns wide at Lesmo. He complains of understeer.

The chequered flag signals that the already-begun laps will count, but no further ones.

Vettel has been out for a last quick run for a few minutes.

The teams are on their long runs and the times are not expected to change.

Vettel still leading the way from Alonso, Massa, Hamilton and Button.

Kubica up to eighth, between the Williams sisters.

Senna has come to a halt again, again near the pitlane exit. The marshals deal with another beached F1 car. His HRT just not up to it this weekend.

Webber, who stands sixth, lost water pressure.

Ferrari escaped a points deduction for manipulating July's German Grand Prix because of past inconsistencies in policing the rules and support from rival team.

The marshals have been busy at Monza today... they wheel it away through the barriers.

Webber touring half a lap from the pits.

Vettel also on a hot lap... 1:22.839 for P1!

And team-mate Alonso goes quickest with 1:22.915!

He put two wheels on to the grass at Parabolica and went flying through the gravel, lifting a dust cloud... he was perilously close to the wall but managed to keep the F10 away from it and guide it back on to the track. Back into the pits of course.

Massa going quick as he heads into the final sector... BUT HE RUNS WIDE AND ALMOST SMASHES INTO THE BARRIERS!

Alguerusari pulls up after the Roggia chicane. He gets out and marshals wheel the Toro Rosso away... the yellow flags are naturally out.

Massa goes top of the pile with 1:23.061.

Senna comes to a halt in the pitlane again!

Kamui Kobayashi off at Lesmo.
