Mercedes boss Toto Wolff has stated that Lewis Hamilton is unlikely to suffer with a "very unusual" engine failure that Valtteri Bottas had in practice on Saturday.
It was a hydraulic problem for Bottas just before the end of FP3.
"We've just heard that Valtteri's reliability issue shouldn't affect Lewis' engine," Wolff told RaceFans on Saturday. "Nevertheless, it is a reminder how fragile the situation is and how much everybody is pushing in order to extract performance.
"Reliability will continue to play a crucial role in this championship and that's why tomorrow (Sunday) it's about finding the right focus in finishing the race with the best possible performance."
Wolff confirmed that Bottas' engine will have to back to the team's headquarters to be assessed after its unusual failure: "The failure we have seen on Valtteri's engine is a failure we haven't seen for many years.
"You can call it a very unusual failure with mileage where it shouldn't have happened. So we need to investigate that. The engine is going to go back to England.
"The (High Performance Powertrain) guys and mechanics have done a really incredible job first in getting the engine onto the car in time and then calibrating it in a way so it can run here. That was not trivial. They kind of got it together, Valtteri said he couldn't feel a big difference, that's really making me very happy."
