Dany Kvyat blasted Alex Albon after Sunday's Eifel GP, calling the Red Bull driver "unprofessional" for causing a collision that undermined the AlphaTauri charger's race.
Kvyat and Albon were fighting for a spot in the points in the early stages of the race when the Russian ran wide at the final chicane.
Kvyat rejoined the track ahead of his rival but Albon's momentum allowed the British-Thai racer to get the measure of the AlphaTauri only to move over and clip the latter's front wing, a contact that forced Kvyat into an unscheduled pit stop and a plunge down the order.
Addressing the incident after the race, Albon, who was handed a 5-second penalty for the mishap, admitted there had been "a bit of misjudgment on my side".
But Kvyat was anything but forgiving towards the Red Bull driver.
"I didn’t understand his manoeuvre really," Kvyat said. "What was he doing?
"I think it was quite unprofessional of him and poor judgement, so you wouldn’t expect that from a driver of his level, who’s been racing so long.
"But anyway, the race was pretty much ruined from then on. I had to do the whole lap very slow with the damaged front wing as a consequence.
"It went under my floor, damaged my whole floor, the brake cooling, and the race from there was really a struggle because the car was massively down on downforce, and I was just really hoping for rain or something really strange to happen."
While Albon emerged unscathed from the tussle, the Red Bull driver ultimately retired from the race on lap 23 due to a pierced radiator.
