Williams poised for best chances of 2014 F1 win at Spa and Monza

The power advantage provided by the team's Mercedes engines, as well as an aerodynamically efficient car, are set to pay dividends at the high-speed Spa and Monza circuits.

Although Bottas says that good results should not be ruled out elsewhere, he knows that there is a real chance of success coming up at the next two grands prix.

"I think in theory Spa and Monza should be the next really good ones for us, maybe the best opportunities of the season," explained Bottas.

"But we need to aim to be strong in other places and we can't just rely on our good top speed and doing well at Spa and Monza."

Williams performance chief Rob Smedley thinks that Spa could be particularly good for the team, and not just because of its straightline speed.

Speaking about the opportunity of Belgium and Italy, Smedley said: "Both of those tracks will suit our car very well I would have thought - mainly due to the fact the power sensitivity at those tracks is very high; every horsepower you have is worth more there than at other tracks.

"The drag sensitivity - especially at Spa - is very high. And we know our car is very strong in those areas.

"Additionally, I think at somewhere like Spa, with harder compounds, it can sometimes be quite difficult to get the tyres turned on and I think our car can do that - especially when it's a front-end problem.

"I'm reasonably confident our car can go well in both of those races, but I've said before that we don't fear anywhere."

STRONG END TO CAMPAIGN

Felipe Massa is bullish about the prospects for Williams over the entire second half of the campaign - and does not view Spa and Monza as the only decent opportunities remaining for victory.

"I think Monza, Spa, maybe USA, maybe Brazil - and also at the last race [Abu Dhabi] you have some good straights," said the Brazilian.

"I think the car can be competitive at many tracks, not just the fastest. Maybe at Spa we can be more competitive than on the others, but I think we need to concentrate and think we can have a good car in most tracks."

When asked if Williams could be ahead of Mercedes on pure pace terms at any of the races, Massa said: "I think it won't be easy, but it's not impossible. Maybe at a few of these tracks we can have more chance."
