Valtteri Bottas says he is 'proud' of the Williams team after it secured third position in the Formula 1 constructors' standings for the second season in succession.

After enduring the hardship of worst season since its 1977 F1 debut in 2013, Williams has bounced back under the current set of technical regulations, finishing third overall in 2014 and now doing the same in 2015 with Bottas' fifth place finish in the Brazilian Grand Prix.

It is a result that the Finn - a two-time podium winner in 2015 - is proud of compared with the financial advantage of the teams around it. Despite this, he still believes the Grove-based team is capable of more going forward.

"It means a lot, because it's nice to secure third," he said. "It's the same as last year, so I'm proud that with such a small team we can fight with the big teams. That's good but we all want more.

"We need to say thank you to people in the race team and at the factory for all the hard work done, but also to Mercedes for their engines. Without them we couldn't do this, but we are a team that wants to win, so we want more."

Though Williams has scored 'only' four podiums in 2015 so far - compared with the seven it managed at the same point in last year's championship -, it is just one point shy of its total points compared with the total from last year's Brazilian Grand Prix. The double points Abu Dhabi decider last year yielded two more podiums for Williams tally in 2014.
