Korea Friday quotes: Williams

Nico Hulkenberg - 16th: The track is pretty nice, I like driving here. We had a good first session this morning but we made some changes to the set-up for the afternoon which didn't take us forward. The car felt quite different and I struggled to get the lap time out of it. We were looking competitive all morning though so we'll go back to what we had originally and improve tomorrow.

Patrick Head, Director of Engineering: It was very interesting to see the track develop and the way both tyres are behaving. I think everyone is experiencing graining on the option tyre, so that may cause some different race strategies. For us, we had a normal Friday, although we'd be happier if our lap times were a bit quicker, but we think we know where that is going to come from.
