"For the race, we hope it'll be closer again and we can make a step forward in terms of looking after the tyres and getting the right strategy," Vettel is quoted as saying by Sky Sports News. "It will be a difficult race but nevertheless we are always optimistic.
"From where we are now, we get an extra set of tyres tomorrow, so maybe that can help us move up. I think generally in terms of pace it will be tricky but I think there's the chance to pass a couple of cars."
Williams's Felipe Massa will start the race in pole position.
