Both of Maranello's drivers are out of contract at the end of the year, and there have some doubts about Raikkonen in particular after Marchionne accused him of being a bit of a 'laggard' earlier this month.

But speaking at the Hungarian Grand Prix, Marchionne suggested that there was now a greater than 50 percent chance that the Finn would keep his place.

Asked about the driver process, Marchionne said: "I think I have been public on the Sebastian issue, if he wants to stay he is more than welcome to stay.

"And in the case of Kimi, we are pretty well sure...we know he wants to stay. Hopefully we will bring them on soon."

Asked about what chance Raikkonen had of securing a new contract, Marchionne said: "Probably better than 50 percent. We will see…"

Marchionne also confirmed that Ferrari was edging towards finalising the line-up by its home race at Monza in September.

"That's what I heard. I heard Maurizio [Arrivabene] was going to do that. I have no planned timing, it is early enough. This is the 11th race out of 20 so we have a lot of races to go."

Hamilton rumours

While there have been recent suggestions that Lewis Hamilton could become a target longer term – especially with his Mercedes contract running out at the end of 2018 – Marchionne said it was too early to consider the Briton yet.

"Ending his career with Ferrari would be a privilege, but until now we did not go very far with Lewis," he said.

"I will not talk about the future. And then we have two great drivers in the house and do not want to talk about alternatives."
