Oscar Piastri slams Carlos Sainz who was fighting Fernando Alonso like it was for the World Championship

It was one of those rare moments when Piastri lost his cool as he went on a rant over the team radio with some colorful language against Sainz.

Speaking to the media afterwards, Piastri reflected on the incident, saying: "He was fighting Fernando for last place like it was the world championship and ‌cost me ⁠the lead of the race.

"He's quite critical of others, and others have given him some stick before for being frustrating on track, and when you go and do something like that, I think maybe you should look in the mirror a bit.

"I don't really care if he didn't see me. The fact ​that he didn't, or no one ​told him, or there ⁠was a lack of complete awareness is unacceptable," the McLaren driver maintained.

Sainz, on the other hand, blamed a system issue, which meant the blue light/flag system was not working ignoring the fact that he had mirrors as well as a race engineer who was supposed to warn him about these situations.

"We ​didn't have blue lights on the steering which normally, when we are in fights like that, where we are fighting for position, helps ​us to understand whether we are getting lapped or not," the Williams driver said.

As for McLaren Team Principal, Andrea Stella, he tried to be diplomatic about the situation cause by the team's former Formula 1 driver.

"My understanding is that the blue (warning) panels were ⁠not working," he said. "So perhaps today was more difficult than normal for the backmarkers to appreciate what ​was happening in their mirrors.

"Carlos is a very fair, very correct driver. So I'm sure that was absolutely unintentional ​but a bit of a shame for Oscar.

"It's absolutely understandable that when you lead the race for almost half [the distance] and then you see yourself losing the lead because of an incident with a back marker then you may have a moment and ​make a comment in anger," Stella explained. (Reporting by Agnes Carlier from the Hungaroring)
