FIA race director Charlie Whiting has spoken with Max Verstappen about his driving with Christian Horner billing it has a "gentle warning" for the Dutchman.
Verstappen angered the Ferrari drivers with his antics in last Sunday's Belgian Grand Prix, however, it is not the first time that his driving has been criticised.
The Red Bull driver has vowed not to change his style but he may have to in the future after a warning from Whiting.
"Charlie was keen to show him a replay of Spa," Red Bull boss Christian Horner told Sky Sports F1.
"It was a gentle warning to say 'that''ll be a black and white flag'. [It was] a bit of a warning."
The race director met with Verstappen at Monza on Friday morning.

As for the criticism that Verstappen received from Raikkonen and Vettel, Horner said: "To be honest with you like any 18-year-old [the criticism] seems to be going in one ear and out the other.
"He really doesn't care, he's focused on his own job, he's not intimidated by the surroundings he's in and I think that's what marks him out as a real talent and star of the future."
