Williams duo make quiet start at Monza

"I had a good day," declared Montoya. "I'm happy with the balance of the car, which gradually improved throughout the two sessions. I think this is going to be an interesting weekend for as we seem to be in good shape on this track."

Schumacher, meanwhile, was also content, but emphasised that brakes would be an issue on race day.

"The track is hard on the brakes," said Schumacher. "Before the first chicane we brake down from around 250 km/h to approximately 70 km/h. For the drivers this is less extreme than it might appear from the outside."

Michelin's tyres have been under intense scrutiny of late, and Chief Engineer Sam Michael underlined the need to maximise grip.

"Michelin have brought two quite different tyres to Monza, and the challenge will be to get the grip in qualifying," said Michael. "Ferrari still has a big advantage on everybody and we will be working overnight to minimise that."
