BREAKING: Red Bull Boss Christian Horner Slams Oscar Piastri Over ‘Unprofessional’ British GP Display — Piastri Fires Back With One Sentence That Leaves Horner Speechless.
In a dramatic turn of events following the British Grand Prix, Red Bull Team Principal Christian Horner has unleashed a scathing critique of McLaren driver Oscar Piastri, accusing the young Australian of “not only underperforming but also displaying unprofessional behavior” during Sunday’s race at Silverstone.
Piastri, who had been on course to challenge for the win, was handed a costly 10-second penalty for a Safety Car infringement — a mistake that saw him tumble down the order and ultimately lose out on a potential maiden victory to his team-mate Lando Norris.
Speaking to Sky Sports F1 after the race, Horner did not mince words. “When you’re racing at this level, you can’t afford rookie mistakes like that — not to mention the way he carried himself on team radio and in the paddock afterwards. It was unprofessional and it cost him and the team dearly,” Horner said. “If you want to beat your team-mate, you do it on track, not by whining or breaking the rules.”
The remarks immediately sparked backlash in the paddock, with many seeing Horner’s comments as unusually pointed for a rival team boss. Piastri, however, did not shy away from responding — delivering a blistering one-liner that reportedly left Horner speechless.
“If Red Bull wants professionalism, maybe they should start with their own garage first.”
Piastri’s retort, referencing the recent tension and controversies swirling around Red Bull’s internal management and driver politics, was met with a mix of gasps and laughter in the media pen.
The penalty and war of words overshadowed what had been a thrilling home victory for Lando Norris, whose flawless drive brought McLaren its second win of the season. Meanwhile, Piastri’s frustration was clear as he crossed the line in P5, after what many believed could have been his breakthrough moment.
Horner declined further comment after Piastri’s pointed response, but insiders suggest this spat may further inflame the rivalry between Red Bull and McLaren as the title fight intensifies.
The Formula 1 circus now heads to Hungary, where all eyes will be on whether Piastri can bounce back — and whether Horner will have more to say. One thing is certain: this new flashpoint has added another layer of drama to an already explosive 2025 season.
