Valtteri Bottas believes his performances so far in 2018 have “more or less” met the targets he set himself prior to his second year with Mercedes.

The Finn has been unfortunate to not add to his tally of three career victories achieved in his debut season for the Silver Arrows last year, with three second-placed finishes recorded in the first five races.

Bottas has been under pressure to deliver consistent results with his future not guaranteed for 2019. Nevertheless, the 28-year-old feels he is in good shape and sights his off the pace weekends from last season as a turning point in his approach.

“I think this year I’ve been meeting more or less my targets with the performance for the beginning of the year,” Bottas said.

“I think I’ve been able to really continue good performance since the very end of last year. There’s been no weekends that I’ve been really way off the pace, like there was a few last year. So I think I’ve learned from those.

“I just need to continue my development, there’s never things that you can’t learn more.”

Bottas currently sits third in the drivers’ championship some 37 points adrift of team-mate Lewis Hamilton, whose back-to-back wins elevated him to the top of the standings. Despite missed opportunities, the ex-GP3 champion remains optimistic of a change in fortune.

“I think there’s been quite mixed races and the end results haven’t been really I feel sometimes quite there, that I feel would have been possible with the pace we have,” he added.

“The gap to Lewis was huge [in Barcelona], but there were many things that affected that.”
