for full FP3 times.
Lewis Hamilton heads in to qualifying for the Italian Grand Prix as favourite for pole position after setting the fastest time of FP3 while Nico Rosberg completed just three laps.
After Hamilton hit trouble on Friday and missed the majority of FP2, it was Rosberg's turn to suffer reliability issues on Saturday morning as a gearbox problem ruled him out of the session after just one run. It is not yet clear if the gearbox requires changing, which would land Rosberg with a five-second grid penalty.
With his team-mate in the garage, Hamilton then proceeded to go fastest by just over 0.4s as Fernando Alonso continued Ferrari's strong form. Ferrari president Luca di Montezemolo was present at Monza, and he saw Alonso finish second quickest and 0.4s faster than team-mate Kimi Raikkonen who ended the session in seventh place.
Williams showed the biggest improvement compared to Friday, with Valtteri Bottas and Felipe Massa third and fourth fastest respectively, both within 0.6s of Hamilton. Behind them was Jenson Button who set the fastest first sector on a medium tyre lap late in the session but scuppered his chances of improving by making an error in sector two.
Sebastian Vettel was sixth quickest for Red Bull ahead of Raikkonen, Daniil Kvyat, Daniel Ricciardo and Nico Hulkenberg, with the top nine cars within a second of Hamilton's time. Kvyat, however, faces a ten-place grid penalty for using a sixth internal combustion engine of the season.
Rosberg wasn't the only driver to have problems during FP3, with Adrian Sutil hit by a hydraulic issue and Sergio Perez stopping at Curva Grande half an hour in to the session after suffering gearbox trouble.
