Rosberg encouraged by practice form

The poor weather at Monza meant Williams were unable to complete their programme during the test last week, so Rosberg and teammate Alex Wurz spent today's practice sessions trying new things.

And Rosberg had a solid day, posting the fifth fastest time.

"Today we went through two or three things that I really wanted to try here last week which we couldn't do due to the bad weather," said Rosberg. "I'm pleased we did them because we gained some helpful results.

"Monza has proved to be a very interesting track for the tyres. We haven't made a decision yet on which direction we'll take and will spend time going over that tonight. Generally, I'm quite pleased with how the sessions went."

Austrian Wurz also had a productive session on his way to the 10th fastest time.

"Practice went ok," he said. "We changed a couple of things in the first session and went for a long run at the end which was very interesting. There's more to come from the balance of my car so I'm working on that tonight.

"Surprisingly, we actually found that today's conditions were relatively the same as those at last week's test, which is good because it means we can use some of the useful data we have collected already.""
