Max Verstappen could not mask his frustration as he swore angrily over the radio about a continuous problem he was suffering in Miami practice.
The defending Formula 1 champion was uncomfortable in the cockpit of his car as he suffered a problem with his headrest. And he made sure his Red Bull team knew about it with a tetchy radio message just a few minutes into FP2 on Friday.
"Mate, my f***ing headrest again. I'm just stuck all the time in my head," he told race engineer Gianpiero Lambiase. And it wasn't long before he was back in the pits so the team could investigate further what the problem was.
