Japan Friday quotes: Toro Rosso

Tonio Liuzzi - 18th: "It is a nice circuit with changes of gradient as it goes up and down, which is something I like in a track, although it is not particularly difficult. It's a really cool circuit and I particularly like the high speed section. It is also really wide, which means that you can try a few different lines although in the end the right line evolves where the rubber goes down

"Overall it was a decent day, with a good run in the morning meaning we could understand what to do in terms of set-up and I learnt the circuit quickly too. On the second run, I did not get a clear lap on new tyres so I think we could have been faster. But I think we got a lot of good data from the long runs regarding set-up and tyre choice, which gives us plenty to work with for tomorrow. A decent Friday."

Sebastian Vettel - 19th: "It's a nice circuit and I prefer the first section that has quick high speed corners, while the last part is technically demanding. There are a lot of possible different lines and it is difficult to figure out which is the quickest, as all of them seem to produce similar speed.

"This makes it harder to set-up the car. Other than that, it has been a normal Friday so there is the usual question mark about fuel loads in the other cars. But my initial feeling is that I am quite happy with how it went today. There are two or three things we can improve. With some work from us and as the track improves, we can move forward."
