Australian GP race quotes: Toro Rosso

Daniel Ricciardo - DNF: "In the end I had to retire with a problem linked to the exhaust. I reported back to the pit wall that I could hear strange noises and I tried to fix it by changing a few functions, but it was not to be. At the start of the race, I struggled to find grip and it felt like I was driving on ice, as it took a very long time to warm up the tyres. But afterwards, after about ten laps, I got up to speed and my lap times were not too bad, but by then I had lost too much time in the early stages. I think we have more homework to do when it comes to the tyres. Not the ending I wanted for the first Grand Prix of the season, especially here in my home race."

Franz Tost: "To look at the positive aspects of this opening Grand Prix first, our car proved to be very competitive in the wet, both our drivers performed well from Friday onwards and, by Sunday afternoon, we had also managed to improve the pace of the STR8 in the dry. However, on the negative side, we missed an opportunity to qualify better this morning, when we did not choose the best tyre strategy and this afternoon, Daniel struggled to find any grip in the early stages and was then forced to retire with a reliability problem. From 13th on the grid, Jean-Eric drove hard to try and get in the points, but was unable to do so. This performance does not reflect our true potential and we must do better, starting in a few days' time in Sepang."
