Mercedes boss Toto Wolff hit out at Red Bull counterpart Christian Horner amid the ongoing row between four-time Formula 1 world champion Max Verstappen and George Russell.
The tension between the pair, which began during qualifying at last weekend's Qatar Grand Prix, escalated quickly after both drivers made further comments ahead of the season finale in Abu Dhabi.
Reacting to the Dutch driver's comments that he had "lost all respect" for Russell for his role in demoting him from pole position, the Mercedes driver said Verstappen had threatened to crash into him on purpose.
And Mercedes boss Wolff also weighed in on the situation by criticising Horner, who called Russell "hysterical" in Qatar, for falling short of his role.
"I think as a team principal, it's important to be a sparring partner for your drivers, and that means explaining that things can be more nuanced," Wolff said.
"Statements that are absolutistic, thinking that everything is 100% right or 100% wrong, is just something you need to explain. Things are more nuanced, depending on your perception and your perspective.
"You need to allow for something to be 51-49, you need to allow it to be 70-30 - so there is always another side.
"Maybe, when you look at it that way, and you explain it to your drivers and your team, you come to the conclusion that there is truth on both sides. If you don't do that, you're falling short of your role."
Verstappen had qualified fastest in Qatar, but was later demoted to a second-placed start after a rare grid penalty for driving unnecessarily slowly and impeding Russell in qualifying, after both drivers had a hearing with the stewards.
"Why does he feel entitled to comment about my driver?" Wolff added. "How does that come? That even thinking about it, I just had 90 seconds to think about it. Yapping little terrier. Always something to say.
"There is a thing between drivers, and this is George and Max, and I don't want to get involved in that. But if the other team principal calls George 'hysterical', this is where he crosses a line for me.
"His forte, for sure, is not intellectual psychoanalysis, but that's quite a word. How dare you comment on the state of mind of my driver?!"
