Nyck de Vries has said that it is only "a matter of time" before he gets his own chance at a career in Formula 1 with McLaren.
The 21-year-old Dutchman, part of McLaren's development programme, said recently that he hopes Stoffel Vandoorne's promotion means he now moves up a rung on the ladder.
De Vries told Dutch publication Helden: "At the moment there are no seats free.
"Next year Stoffel Vandoorne makes his debut so I have to wait for my chance, but it's a matter of time I think.
"If I keep performing well, my chance will come. [Fernando] Alonso's contract expires late next year - perhaps there is space, we'll see."
McLaren sit sixth in the constructors' championship ahead of today's Singapore Grand Prix.
