'Difficult day' for drivers in China
- From the section Formula 1
Mercedes drivers Nico Rosberg and Lewis Hamilton, along with McLaren's Sergio Perez and Jenson Button, assess the "difficult day" after Friday's practice sessions for the Chinese Grand Prix.
Rosberg and Hamilton gave Mercedes a one-two in P1, but Hamilton says the car still feels "uncomfortable".
Ferrari's Felipe Massa went fastest in P2, but while Perez says he is "still learning" from the McLaren, Button believes the team are seeing "an improvement" after a poor start to the season.
