Lewis Hamilton and Sebastian Vettel feel "threatened" by Max Verstappen, according to the young Dutch driver's father.
In Mexico, world champion Hamilton hit out at Verstappen's aggressive driving, and Vettel said he would "copy-paste" that opinion.
"I think Lewis feels threatened by Max," Jos Verstappen told Ziggo Sport.
"Max is getting into their heads, which is not surprising. Give Max a good car next season and then we'll see."
However, Verstappen has been roundly criticised for his behaviour in Mexico, including ignoring the yellow flags and getting involved in collisions in the race.
"The only thing we can accuse him of is that he needs to be a little more diplomatic with his answers," Marko said.body check tags ::
