Follow live coverage of the second practice session for the Italian Grand Prix from Monza with F1i.
The final race of the European season takes place at the iconic Autodromo Nazionale di Monza this weekend, with Lewis Hamilton holding a nine-point lead over team-mate Nico Rosberg in the drivers' championship following Hamilton's fightback in Belgium last weekend.
It was Rosberg who topped the times in the opening session on Friday morning, beating his team-mate by 0.2s on the soft compound tyre. While the margin to the rest of the field was over a second, Mercedes improved on the softs compared to the supersoft tyre as it again struggled to get the most of the red-walled Pirellis.
By contrast, Ferrari has yet to use the supersoft and was third and fourth with Kimi Raikkonen and Sebastian Vettel respectively. The Scuderia will hope to be able to extract more performance from the supersofts when they are used later in FP2, in order to close the gap to Mercedes.
Force India again looked strong on Friday morning but Sergio Perez - fifth fastest - set his best time on the supersoft tyre, as did Romain Grosjean in sixth for Haas. Haas actually had both drivers in the top ten, with both Haas and Ferrari running an updated power unit which saw the last of Ferrari's development tokens used.
