Ferrari team boss Fred Vasseur has revealed that their decision to put Carlos Sainz on the soft tyres for Saturday's sprint race at the United States Grand Prix was a tactic to try and gain some extra data for Sunday's race.
Now, Vasseur has revealed that the team used the sprint race as an opportunity to gain more information about how both sets of tyres will react during Sunday's main race.
“We spoke this morning, and we thought it was essential for us since we didn’t have the same strategy as the other teams, to try the soft tyres with Carlos to have some data for tomorrow’s race,” he told Sky Sports Italy after the sprint.
”I’m not satisfied with the race today, and I think we should’ve done so much better, but we needed to try different types of tyres to see how they would perform during a race.
"It will be a challenge tomorrow, but Max is starting P6, so we must be good at keeping him behind. The first lap is going to be crucial tomorrow.”
