Renault have admitted that their driver lineup for 2017 remains totally open.
Reports have suggested that Jolyon Palmer is in danger of losing his seat at the newly-reformed French works team, while teammate Kevin Magnussen is more confident of staying next year.
However, neither is under contract for 2017 and team spokesman Andy Stobart told Danish newspaper BT that the lineup will remain unknown for some time.
"It's too early for us to start discussing what should happen next year," he reportedly said.
"We are more focused on this year and the rest of the season. We are only halfway, so it's too early."
"There is nothing definite on our part, and the rest is just speculation," said Stobart, amid speculation that Esteban Ocon is in the running for a seat, as may be Felipe Massa and Stoffel Vandoorne.
It is believed that Renault have an option to keep Dane Magnussen on board for 2017, but Stobart would not be drawn on when it expires.
"It's a private matter between us and Kevin Magnussen," he insisted.
However, the report notes that F1 options typically expire around September, which would tie into reports that other teams plan to look at their own lineups around that time.
