The three-time world champion had a difficult outing at the Hungarian Grand Prix, getting involved in a collision for which he found himself under investigation from the FIA.
After running wide at Turn 1 and losing out to the McLarens during the opening stages of the race, Verstappen became increasingly frustrated over team radio.
Over the course of the grand prix, Verstappen hurled a series of x-rated team radio messagesto his engineer, Gianpiero Lambiase, criticising Red Bull’s strategy.
His frustration culminated in a crash with Lewis Hamilton as he attempted an overtake down the main straight, but instead locked up and made contact with the Mercedes.
As his Red Bull launched into the air, Verstappen failed to challenge his rival for P3 and tumbled down the order into P5.
The Dutchman took part in the ‘24 hours of Spa’ sim racing event the night before the Hungarian Grand Prix, which reportedly kept him awake until 3am.
Speaking to Sky Germany Christian Horner admitted Verstappen’s sim racing was a ‘problem’ but it had been resolved.
“Fortunately there are no more races this season,” he said.
“So the problem took care of itself. We had a pretty positive Friday today, we collected some data that we now have to look at and hopefully we will end on a positive note at the last race before the summer break.”
