A developing driver has left McLaren.
"I don't want to sound arrogant at all, but Norris and Albon were really no better than me," the 24-year-old said.
But now, De Telegraaf newspaper reports that de Vries has stopped working as McLaren's simulator driver.
"I no longer do simulator work for McLaren," he confirmed.
"Will I for another team? I can't say anything else about it," de Vries added.
"Ultimately, it will be all about what I am doing here," he said, referring to Formula 2 and his chances of moving up to F1.
"That will have the most influence on my future, so I am mainly concerned with that."
