De Vries confirmed in September he had held discussions with Red Bull supremo Marko about driving for AlphaTauri but admitted that a move to Williams would have seemed like the obvious step to make after making his debut with them.
“I don’t quite know if I’m in such a luxury situation that I can choose,” he said, as reported by Motorsport.com. “Largely, that is beyond my control. I have been in talks with Williams for a long time and I was also able to make my debut there last weekend.
“That would be a logical step. Alpine I have been in contact with them since July, and I will test for them in Budapest next week. I will fly there on Monday. And as the media had noticed yesterday, I went to Austria to meet Helmut Marko. Those are the facts.”
