Ferrari chairman John Elkan at Bahrain International Circuit in Bahrain
Ferrari chairman John Elkann says the company's Formula 1 drivers Lewis Hamilton and Charles Leclerc "need to focus on driving and talk less".
Elkann's comments come on the back of a Sao Paulo Grand Prix last weekend in which Ferrari suffered a double retirement and Hamilton described his maiden season with the team as a "nightmare".
Ferrari dropped to fourth in the constructors' championship as a result of the race. They are 36 points behind Mercedes and four adrift of Red Bull with three grands prix and a sprint remaining.
Elkann said at an Olympics sponsorship event in Rome on Monday that the team's mechanics and engineers were performing well, but "if we look at the rest, it is not up to scratch".
