Valtteri Bottas is keen to stay with Williams for 2015 and says he doesn't believe the team has reached its peak yet.

2014 has seen Bottas take his first podium finish as he currently sits in fifth place in the drivers' championship after 11 races. Currently in his second year with Williams, Bottas has yet to sign a contract for next season but says he doesn't see any reason to seek a move elsewhere. Asked where he sees his future, Bottas replied: "We will see.

"It's still too early to say anything about that really but personally I don't see a reason to look around at this moment. But it's too early to say, it's better to wait for confirmation but we will speak when we have something to say."

And Bottas is confident Williams can improve further after emerging as the closest challenger to Mercedes at the majority of circuits this season.

"I really think this team is not at its peak yet. I really think the way it is now, the direction is right and I am confident this team can still be better than what we've seen this year. So that's why I am really confident here and wouldn't mind continuing here."

However, Bottas doesn't expect to see Williams make any major strides in terms of car development between now and the end of the year, with the team focusing on developing next season's car.

"[We will have] small things here and there. Small aerodynamic bits, a bit of mechanical stuff but nothing mega. We still aim to bring some small things here and there, especially at tracks where we have more work to do where we need more downforce. But everyone is definitely focusing a lot to next year's car and have been already for a long time, so hopefully others don't really improve that much because I don't see anything massive on the radar."
