Ralf Schumacher has rebuked Isack Hadjar’s fury that was aimed at Red Bull during last weekend’s United States Grand Prix.

The Frenchman was furious with his team during the 56-lap Grand Prix at the Circuit of the Americas on Sunday, with several issues hindering his chances of securing a third podium finish for Red Bull in 2026.

Are you worried about Isack Hadjar after his reaction to crashing in Miami?

It’s not the first time Hadjar has openly criticised Red Bull from within the cockpit either. During the Hungarian Grand Prix in July, Hadjar demanded changes to his RB22 after branding it ‘undrivable’.

Hadjar’s emotional outbursts have been called into question in the past, and Ralf Schumacher is now the latest figure from the F1 paddock to weigh in with his thoughts on the 22-year-old’s antics.

Ralf Schumacher says Isack Hadjar’s fury with Red Bull ‘does not belong’ in F1

During Sky Sports Germany’s live coverage of last weekend’s United States Grand Prix, Schumacher told viewers that he thinks Hadjar ‘needs to take it down a notch’.

The verdict came after Hadjar began to scream over the radio about the drivability of his RB22. During his first and only pit stop, the Parisian failed to change his engine map back to its usual race strategy, meaning he was stuck in the pit-lane mode for the remainder of the race.

What is Isack Hadjar's ceiling as an F1 driver?

According to Hadjar, the error cost him around one second per lap, which threw out any hopes of him converting his P3 grid slot into another podium for the Austrian constructor.

Still, Schumacher firmly believes that his tirade over the team radio simply has no place in the sport.

“Nevertheless, the team praised him afterwards and said, well, that was actually a good result given what we were able to achieve here; we made the best of it.

“So, that’s fine, which is something I can’t quite say for his teammate, because I think this is now the second time. I wouldn’t say it’s a lack of decency, but it’s not the sort of behaviour one should expect from him.”

After detailing how Helmut Marko certainly would not have allowed Hadjar’s attitude to fly if he were still at the team, Schumacher added: “It’s clear there are problems, but he’s not exactly flawless either.

“When you talk about the issue so intensely and so frustratedly – and in that manner – then I have to say quite honestly that, in my view, that sort of behaviour does not belong in Formula 1.”
