It's not often that you hear a team principal tell their driver to "shut up" over the team radio, but that's what happened to Romain Grosjean in the United States Grand Prix.
The French driver does seem to have picked up a reputation for endlessly complaining during a race weekend, and in large part that's due to his understandable racer's frustration about getting the car handling set up to a point where he can be competitive. He certainly managed it at the Red Bull Ring where he finished in sixth place as 'best of the rest' behind the combined ranks of Mercedes, Ferrari and Red Bull.
Overall he won the lion's share of the team's championship points, and out qualified his new team mate by 12 times to seven. But it's actually been a fairly even battle with Kevin Magnussen in 2017 and the pair appear well-matched heading into another season together in 2018, meaning that Grosjean will certainly be kept on his toes.
