Daniel Ricciardo admits he's become a "Sunday driver" and that qualifying was his weakness in an ultimately disappointing 2017 season.
The Australian's best performance came in Baku when he won his only grand prix of the year, but he scored 56 fewer points and ended up two places further down in the drivers' championship compared to his 2016 campaign.
Qualifying had been a strength of the Red Bull star in previous seasons but he acknowledges he struggled to get to grips with the new generation of F1 machinery over a single lap.
"I used to be called a Saturday driver, now I feel I'm probably called a Sunday driver," Ricciardo told Autosport. "Who would have thought?
"I'll put it down to a couple of things. I wouldn't say I've struggled with the car but it's been a bit trickier to maximise.
"There were a lot of laps on Saturdays... I mean I crashed twice in qualifying which is very uncharacteristic - Australia and Baku - where it was trickier certainly."
Ricciardo believes he was "too sensitive" to the new car at the start of the season which allowed team-mate Max Verstappen to out-perform him in qualifying.
He added: "For whatever reason, Max didn't find it as complicated to start the year. Naturally, I was probably too sensitive to it as well.
"A lot of the time, it was probably better to just drive it and deal with the grip I had as opposed to try and fine-tune it too much."
