Williams driver Valtteri Bottas says he has been left dissatisfied by his 2015 results, as the flyaway leg of the Formula 1 season begins in Singapore this weekend.
Bottas scored six podiums on his way to fourth place in the 2014 standings but this season has stepped onto the rostrum just once - in Canada - and sits in sixth position in the championship.
"Well I have to say I’m not really that pleased for the results," he explained. "Of course we aim to make a step forward. I think we’ve improved from last year but, compared to others, not really.
"So, as a team, I think everyone in the team is expecting more and we are aiming to do better in the future and obviously I’m staying with the team so it’s very nice to start building from this because I still think we’re not yet at a peak and we can definitely do better.
"From my side also, it’s been a very mixed season. A lot of things have not been going to my side, so unlucky races, unlucky results. That’s how it is sometimes."
Bottas joked that there are two fundamental aspects where Williams needs to find improvements.
"Downforce! And power! That’s what keeps you going. I think as a team we really need to improve in all areas like we’ve seen we’ve had quite a few issues still with pit stops and some mistakes from us, as a team," he commented.
"We’re still just getting stronger in all areas. Unfortunately, sometimes the way to improve is to do that mistake and then learn from it. I’m sure that soon there will be no more mistakes we can do."
