Grosjean missed a lot of running in the first practice session due to a technical problem and was heard repeatedly complaining about his tyres in the second session.
Romain Grosjean: “It’s OK when the car is really balanced and the baseline is good but I think our baseline was very, very far from what we’ve been running at the end of the day.”
Romain Grosjean: “So at the end I ran five laps in the morning and one set of tyres the whole afternoon.”
However Grosjean said he was happier with his car’s balance by the end of the day.
