Haas Formula 1 team boss Gunther Steiner believes his driver Kevin Magnussen was right to hit back at "bully" Nico Hulkenberg after their Hungarian Grand Prix run-in.
Renault driver Hulkenberg was angered by Magnussen's robust late-race defensive driving and approached the Dane during media interviews to sarcastically congratulate him on being "the most unsporting driver".
In response, Magnussen told the German: "Suck my balls, honey."
Talking to the media afterwards, Steiner argued Magnussen's defensive move - which resulted in a five-second penalty - was not over the limit, and criticised Hulkenberg for having clashed with Haas's other driver Romain Grosjean at the first corner of the race.
"Nico was the guy who destroyed Romain's race," Steiner said. "And then we get a penalty with Kevin.
"Kevin did the right thing and stood his point there, in my opinion. Why would he lift?
"It's a tough battle, and Nico went to the stewards to ask for a harsher penalty of Kevin, which I think is childish, immature.
"Who has ever done that? I'm almost speechless.
"I respect Nico as a driver and as a human being, but what he did there - you don't ask for a more severe penalty for somebody."
Asked by Autosport whether Magnussen was right to use the words that he used in talking to Hulkenberg, Steiner stood by his driver: "It's the right way to say it. Why would he say anything else?
"He got a penalty, if he [Hulkenberg] thinks he [Magnussen] needs more [of a penalty], then he [Hulkenberg] needs to look at his Turn 1 incident.
"Is it sporting to run into Romain? [Hulkenberg] is a bully and he got away a long time with it and maybe now it's time that somebody stands up to him.
"He's a good driver, he doesn't need to be like this."
Steiner said he was planning to speak to Hulkenberg when F1 reconvenes at Spa after the summer break.
