Bottas says he'll be aggressive when F1 wins are on the line

The Finn has been consistent this season, finishing in the top six in seven of the nine F1 races he has contested, and while he does not intend to change that approach, he thinks he has an extra gear.

"If you want to get some good points or if you want to win the race, first you need to finish the race," he told AUTOSPORT.

"If you take risks, it's better to take calculated risks then silly ones.

"I calculate things ahead quite a lot, considering if it's worth taking a risk or not.

"My style is always consistent, but I think that probably many people haven't seen that when it counts for the win.

"In fighting for the win, or with important positions, I can be aggressive so I think at some point we will see that."

Bottas concedes that Mercedes will be difficult to beat this season, but he remains hopeful that a maiden victory is still a possibility in 2015.

"Mercedes is so far ahead at this point that I think it could be possible if they were for some reason unlucky, but then we would also need to be in front of the Ferraris," said Bottas.

"I think if we could catch Ferrari then that dream might become closer.

"We've been on the podium in a couple of races this season so that's good - it's not bad, but obviously we want more.

"The most positive thing is that we've been able to score more points at the beginning of the season than what we did last year.

"As well as that, all the bits we put on the car always make the car quicker so that's a good thing.

"If we can continue that then we can be closer.

"Winning - I don't say it's impossible; it's tricky at the moment but of course we always try."
