Toro Rosso youngster Daniil Kvyat says a top five finish is his aim after achieving the best grid slot of his Formula 1 career at his home race in Russia.
Kvyat set the fifth fastest time in qualifying at the Sochi Autodrom - the highest position a Toro Rosso driver has achieved since Daniel Ricciardo last season.
"It feels great securing fifth in today's qualifying here in my home country," he said.
"It was already looking quite promising yesterday, so I'm very happy we could put it all together and achieve my best ever Qualifying result today. The car felt very good and everything worked out well, so well done to the team. I will do my best in tomorrow's race and I will definitely aim to finish the race at least in fifth position."
Team-mate Jean-Eric Vergne was 10th and admits he needs to find out why he was so slow.
"I was extremely slow today and I don’t know why," he said.
"I lost time everywhere around the track and I’m wondering if there was a problem somewhere, which did not allow me to get the best out of the car. We will have a look at all the data, trying to understand what happened and be quicker again tomorrow."
