While Force India enjoys a 28-point lead on the Constructors' Championship, Williams driver Valtteri Bottas has urged the Grove-based outfit to go all-out as he and his team-mate suffered a disappointing afternoon in Interlagos.
Locked in a fierce battle for fourth with Force India, Williams suffered a blow as both Nico Hulkenberg and Sergio Perez finished in the points, while Bottas and Felipe Massa left Brazil point-less.
Looking ahead to the last race of the season, the Finn insisted Williams should pull out all the stops as they have nothing to lose, adding that Abu Dhabi will suit their car better.
"We must just go for it! It's the last race, we have nothing to lose," Bottas said.
"We obviously will have nothing new in the car, normally it should be a better track for us and, at least, it should also be dry.
"It is disappointing, they [Force India] had a very good race, they had a good strategy and you also need a bit of luck in these conditions.
"It wasn't our day and it was also a shame for Felipe that his last home race finished like this, but I'm sure he still got a pretty warm cheer from the fans.
"The pace in wet was actually more or less like our pace in the dry, so that was okay, after all the struggles we had in wet conditions in the past."
