Korean GP race quotes: Toro Rosso

Daniel Ricciardo - 19th: "I think we did all we could today in the race. I had a decent first stint and tried to run as long as possible on the Prime tyre. The car wasn't perfect but it was good enough to be in a points position with a few laps to go and I was hanging on nicely to ninth. It's déjà vu, as I had the same scenario here last year, when I came down to Turn 3 with a few laps to go, I braked and the car immediately shot to the left. That time it cost me one place. Once I got out of the cockpit this time, I could see there was a mechanical problem at the front left corner. Personally, I was really pleased with my performance in the car today. Maybe we didn't have a top ten car but I was able to fight in the top ten. But for myself and the team it's frustrating to get no reward. Now all we can do is look ahead to Suzuka."

Franz Tost: "Daniel was the only driver to start on the Medium tyre as we wanted to try something different on the strategy front to make up some places. It seemed to work well, as he made up a few positions by mid race. However, the Safety Car came at the wrong time for him, but we had to bring him in, knowing he would have a tough final stint on the Supersofts. But he did a good job of managing his tyres and defending his ninth place quite comfortably. Then with two laps to go, we had a mechanical issue on the car which we will investigate when we get it back and he had to park at the side of the track. Jev had a harder afternoon, starting from further back and, after making up a few places, the heavy traffic in the back of the field meant he had higher tyre degradation. We decided to switch him to a three stop strategy, but in the end we had to retire him with what might be a similar problem to Daniel's car."
