We've lost points to Ferrari in the Constructors' battle at the last two rounds, but while we know there's a tough fight ahead, we're fully focused on securing the double and ending the year in style.
"Our target for this season was to win both Championships, not one title or the other, so our mindset is one of unfinished business as we head to São Paulo," Toto said.
"We have a big battle on our hands for the Constructors' title and we have lost ground to Ferrari in each of the past race weekends - even though we had the base performance to do better.
"This is the moment to keep our feet on the ground, focus clearly on the objective and trust in our processes and people to deliver.
"In the cockpit, I know that both Lewis and Valtteri are determined to end their respective seasons on a high note; as a team, we are aiming to finish this year with our heads held high and with two performances that properly reflect the level of performance we have attained this year."
