China Saturday quotes: Bridgestone

What was significant about today's running?

"Qualifying was very interesting and congratulations to Sebastian Vettel for a very intelligent pole position where he managed our soft compound very well. The key to a fast qualifying lap here today was to conserve the soft compound tyres through the first sector to be able to push harder in sector two and three. Pushing too hard in sector one meant that there was not the same amount of rear stability from the tyres in the second two sectors."

What are the tyre strategy considerations for tomorrow's race?

"Assuming it is dry, all of the top ten competitors will start on the soft compound. Only considering the tyre performance we would expect people to make their first stops from around lap 20. Through tyre management drivers should be able to make their tyres last longer than this, and it will be good to see who opts for which approach. Rubens Barrichello is the first driver in the field who can choose his starting tyre, so we will watch his decision keenly. Of course, there are many predictions for wet weather tomorrow, but as we saw in Malaysia, weather predictions cannot always be believed."
