Sebastian Vettel reckons that he missed out on third position during qualifying for the Russian Grand Prix at the Sochi Autodrom.
Vettel was edged out by Williams rival Valtteri Bottas and will start from the outside of the second row on the grid.
"I’m not entirely happy: I think that qualifying was close and third place was possible," he said.
"We started very well in qualifying, needing only one lap in Q1; then… I don’t know, as qualifying progressed I lost a little bit of feeling and didn’t manage to put the lap together in the end.
"Maybe there’s some ideas why this happened, we’ll have to have a look at that; but to be honest it’s irrelevant because tomorrow it’s a different format, a race with many laps, so we have to see what the day brings.
"We didn’t have the opportunity to really change much on the car, but I think everybody is in the same situation.
Vettel is nonetheless confident that he can challenge Bottas during Sunday's race.
"Strategy is a bit unknown at that point, but we’ll try to do our best," he said.
"I think is possible to fight with Williams, I believe we have a very good car so it should be a good race: I’m actually very confident for tomorrow.
"As for Mercedes, I think they have been more or less one second away but I also think tomorrow it will be a lot closer, I expect that the gap will be smaller, but we’ll see what we can do. If we have the chance, of course we must take it."
