Stoffel Vandoorne is "lucky" with the timing of being promoted to a race seat at McLaren, according to the team's former driver Kevin Magnussen.
Jenson Button, the 2009 Formula One world champion, announced in September that he would be stepping down from a race seat next season and he is unlikely to return to the F1 grid.
Vandoorne, 24, was consequently promoted from reserve driver to partner two-time world champion Fernando Alonso for 2017.
An overhaul of F1's aerodynamic rules next season has left McLaren optimistic that they can once again compete at the front of the grid and Magnussen believes Vandoorne is fortunate with the timing of his promotion.
"I don't need to give him any advice. He knows how to do it himself. And he has some people there to support him," he told Motorsport.com.
"And I think he's been very lucky to come into Formula 1 in a very good time - come into McLaren in a very good time. I think a lot of good things are happening there. And I think it is a very good place to be at now.
"[In Alonso,] he is up against one of the best in the sport. He will be able to show properly what he can do, because of that. So I think he has everything that you can ask for to make a future for yourself in Formula 1."
