Sebastian Vettel may hope Kimi Raikkonen remains at Ferrari next year, but if it was up to David Coulthard then the Finn would be replaced by Nico Hulkenberg or Valtteri Bottas.
Raikkonen's contract with the Scuderia runs out at the end of this year and, although he has indicated that he would love to stay with the team, he hasn't really delivered on track.
While Vettel has won one race this year and appeared on the podium another four times, Raikkonen has just one top-three place to his name.
Vettel, though, wants Ferrari to retain the Finn saying "Kimi will soon return to being the driver we all know".
However, Coulthard feels Ferrari should replace the 2007 World Champion with either Force India's Nico Hulkenberg or Williams driver Valtteri Bottas.
"The question is, is Kimi better value for money for Ferrari than say a Hulkenberg or a Bottas? One of these younger guys who are on the rise," Coulthard is quoted as saying by Autosport.
"If I was Ferrari, I would seriously look at who could be the replacement for Kimi. Marketing-wise, it's one aspect of what he brings, but in the end the best marketing is a winner.
"Bottas has a contract at Williams, but of course everything has a price, and Ferrari can afford to pay that option.
"I think Hulkenberg deserves a chance in a top car. He's won everything in his career and, OK, he didn't single-handedly win Le Mans, but it's a nice story to remind us that he's a winning driver.
"I've got to believe he's worth a chance."
As for Raikkonen's form this year, Coulthard believes it is time for the Finn to call it a day as he is no longer producing the performances that everyone knows he is capable of.
"I think it's time for change," he said. "I'm not anti-Kimi at all, but having lived through that experience myself, there's a point in your career where you just stop getting better.
"It happened to me in my career; I was never the best driver, but there was certainly a point at the end where you just lose the edge.
"Right now, if Kimi goes and wins the next race, we'll all be super-excited, because we need that. But Vettel's come in and immediately established himself.
"When he was there with [Fernando] Alonso, Alonso was better.
"The facts are that whether it's bad luck or something else, he hasn't delivered in the last couple of years at the level he did in his previous career."
