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

D'Ambrosio opens the session with a 1:30, while Bruno Senna - absent from this morning's session - is now out on the circuit.

Jerome D'Ambrosio gets straight out onto the track, no doubt wanting plenty of laps to get used to his maiden race weekend in F1 as Romain Grosjean's stand-in.

Fernando Alonso's car looks nothing like ready - the championship leader is kicking back in the pits with his overalls pulled round his waist.

The session begins, and Caterham's Vitali Petrov is the first man out of the pits.

Schumacher looked very slick in the opening practice here, but if he does decide to retire it seems he has an option:

Still stunning weather in Italy: 27 degrees, with the track now at 40 degrees - that's 9 degrees hotter than this morning.

Michael Schumacher was the class of the field this morning as he topped the timesheets in the opening session, in which many struggled for grip.
