Max Verstappen suggested Sebastian Vettel should "go back to school" to learn some nicer language after the German's radio meltdown in the closing stages of the Mexican Grand Prix.
Vettel caught up with Verstappen in the closing stages of the race, forcing the Red Bull driver into a mistake across the grass at Turn 1 with three laps to go. However, immediately after that, Verstappen refused to give up the position, despite being advised to by Red Bull, prompting an expletive-laden rant from Vettel.
Verstappen said Vettel's recent demeanour on radio has been "ridiculous" and, despite being the youngest driver on the grid, suggested the Ferrari driver seek out some language classes.
"I don't know how often he's using very bad language in general but I think he has to go back to school or something to get some better language," Vettel said. "I will speak to him because it's ridiculous the way he's handling it. He's always so frustrated, the whole weekend he's just shouting on the radio. He's just a frustrated guy at the moment."
Verstappen refusing to yield position meant his Red Bull teammate Daniel Ricciardo closed up to Vettel, with the pair nearly colliding at Turn 4 as the Ferrari driver appeared to move under braking to defend fourth position. Vettel has previously criticised Verstappen for doing the same and the Dutchman could not resist a little dig at the four-time world champion's driving late on.
"I saw the footage already. At least I can do it in a good way, because it's ridiculous what he did. Daniel is alongside him and he just turned into him. They touched and then he started shouting on the radio."
Verstappen crossed the line third but was immediately handed a five-second penalty, demoting him to fifth. Verstappen questioned why he was penalised when race leader Lewis Hamilton and Mercedes teammate Nico Rosberg went wide at Turn 1 at the start and were not.
"I think it's pretty similar to what happened in lap one, corner one, Lewis went off and gained a massive advantage. Nico also went off at Turn 1 when we touched, he also gained an advantage.
"[With Seb] I didn't even gain an advantage, I was still ahead under braking, when I came back on track I was same length in front, so I think it's ridiculous"
