Drivers in dark as Renault delays 2017 Formula 1 line-up decision

Magnussen told Autosport after the Italian Grand Prix he expected to know his fate coming into this weekend's F1 race in Singapore.

But Magnussen remains in limbo, along with team-mate Jolyon Palmer, as well as rival Renault contenders Sergio Perez and Esteban Ocon.

Renault's delay appears to have swayed Perez into remaining with Force India as he too had hoped to have confirmed a move to the French manufacturer by now.

But with no progress being made behind the scenes, Perez said: "I was hoping to be in a position to announce my plans for this weekend.

"Obviously we got some delays, but I really hope before the next race we can definitely announce where I'll be racing."

Asked for a hint, he replied: "Well, I always say I'll be very happy if I can stay, if everything is fine for me to stay where I am."

Magnussen conceded to being in the dark with regard to his future.

"I don't know what's going on behind the scenes," said Magnussen.

"I've read in the press there has been a delay, and the decision could take a long time, which is frustrating.

"I was hoping for a decision in between these two races [Italy and Singapore], but clearly it hasn't come and things are taking longer than I'd hoped for."

Autosport understands the option Renault has on Magnussen for 2017 expires at the end of September.

The 23-year-old Dane suggested once that point arrives then he will take matters into his own hands as he needs to sort out a drive for next year.

"Hopefully there will be a decision at some point, otherwise I'll take it," added Magnussen.

"I'm a racing driver, I need to race, I can't wait around until one week before the first test. That's not an option for me, so we'll see what happens."

Magnussen insists the situation he is going through at the moment is different to that he experienced at McLaren, when he believed he was assured of a 2015 race seat after his '14 debut only to end up as reserve instead.

"The situation at McLaren was easier in a way because I thought I knew I had the seat, and I wasn't so worried, until maybe the last two races," said Magnussen.

"So at this point in the season I feel very comfortable, I don't feel too stressed to be honest.

"It would be nice to know your future and be a little bit more relaxed. That's not what I have, but anyway, that's how it is."
