Reigning world champion Sebastian Vettel has acknowledged that he faces a tough race in Sunday's Austrian Grand Prix, but remains confident that he can make progress in the standings.

The Red Bull driver finished today's qualifying session in 13th place, with teammate Daniel Ricciardo finishing in 5th.

"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.
