McLaren have put down the initial marker for the weekend, then, with both cars at the top end of the timesheets. Klien has to hand back his car to Chandhok for the second Friday session, which gets underway very shortly.

Weather update

We've got more sunny intervals on the way today, whilst tomorrow it looks as though we could see some heavy rain. The forecast for Sunday at the moment looks like drizzle, which is the worst kind of rain for F1 - it will make barely any difference.

One to watch

Pedro de la Rosa couldn't set a laptime in FP1 due to a gearbox problem with the Sauber. He completed just three installation laps. Now, the man should know Barcelona inside out, but a lack of running could hinder him for the rest of the weekend.

Predictions please

Who will finish the day on top? Will Schumacher manage to beat Rosberg for two sessions in a row? Will the rain hold off? Will anyone crash? Who will head out on track first?
