Williams's primary focus for the remainder of 2014 is to beat Ferrari to third place in the Constructors' championship, according to head of vehicle performance Rob Smedley.

Williams has enjoyed a revival in 2014 following a dismal 2013 campaign in which the Grove-based squad amassed just five points.

This year, the outfit has claimed 177 points and five podium positions to lie third in the teams' table, 15 points ahead of Ferrari.

Smedley says that their aim is now to resist Ferrari across the remainder of the year and cement their current position, starting in Singapore this weekend.

"The track has a few issues that we have to work around, such as the lack of grip that on a normal track would improve, but here doesn’t," he said.

"This results in a lot of wheel spin and oversteer which affects the balance of the car. The main focus for the team is the Constructors’ Championship now and we have to establish ourselves in third position, which we regained from Ferrari in Monza."

Valtteri Bottas, who has taken four of Williams's podiums in 2014, is hopeful that the team can be 'best of the rest' behind Mercedes.

"The race is long," he said of the 61 lap affair at Marina Bay.

"Normally it goes up to two hours, so it’s a challenge for the cars with tyre degradation, and for the drivers physically it will be probably the toughest race of the season due to the heat and humidity.

"Singapore could be a little more difficult for us compared to Monza, but we have some aero upgrades which should give us more downforce. We go there hoping to fight with Ferrari and Red Bull but we know Mercedes will be very strong."
