Aston Martin have refused to rule out the possibility of Sebastian Vettel making a shock comeback at the season-opening Bahrain Grand Prix.
Team principal Mike Krack admitted he had spoken to the four-time champion since Aston Martin's Lance Stroll was forced to miss pre-season testing.
But he refused to say whether Vettel, who retired at the end of last season, had expressed an interest in being a stand-in.
Stroll has suffered a wrist injury.
Krack said "Plan A" was for Stroll to recover in time for next weekend's race.
He added: "Plan B we will speak about next week."
Krack said: "I have had a couple of phone calls with Sebastian but this has been also [the case] last year and will continue in the future."
Asked whether Vettel had said he was prepared to come back in the event Aston Martin needed a driver to substitute for Stroll, Krack said: "I will not tell you."
"First our plan is to have Lance in the car and then we continue to see," he said, adding: "You can ask me five times, we have not made a final decision."

Alonso vs Vettel.. That will be fun to watch.
If you’re their reserve driver you’ve gotta be pissed off. I personally don't see this happening. I doubt Vettel would be fit enough.
