Pirelli's Motorsport Director Paul Hembery: "Conditions were particularly tough today because of the heat at Monza as well as the usual high speeds, so we didn't see much evolution of the track from the morning to the afternoon. Despite this heavy punishment, the tyres performed well - especially the medium, with Lewis Hamilton making the most of the cooler conditions in the morning.
"We're analysing the data throughout the afternoon, but there appears to be no blistering outside the usual parameters for this circuit. From a company point of view, it's an amazing feeling to be racing here on our home territory and we've enjoyed some fantastic support from all the fans here so far.
"With six drivers within half a second of Sebastian Vettel this afternoon and two extensive DRS zones, it's going to be a very fast and closely-fought qualifying session tomorrow."
