Valtteri Bottas revealed that he expected to achieve more than the 15th place grid position he finished with for Sunday's Abu Dhabi Grand Prix.
The Williams driver had a promising practice session on Saturday but was caught in traffic during the second part of qualifying, and the Finn believes that there is more to come from his car.
He told reporters: "I was expecting that we would be fighting for a place in Q3 so I'm a little disappointed."
"It's not the best place to start the race but we know that around this track we can be quite strong on long runs so I expect that we will be able to move up tomorrow."
Bottas is yet to score a point for Williams since joining the team last winter.
