Ferrari president Sergio Marchionne says it is more than "50percent probable" the driver line-up will remain the same in 2018.

Sebastian Vettel and Kimi Raikkonen have been the Scuderia's drivers for the past three and four years respectively and the duo have formed a good relationship since becoming team-mates in 2015.

The good team spirit was highlighted in Hungary last time out as the Finn opted to stay in second despite having the extra speed to pass the German, who was battling a steering problem throughout the race.

Vettel ended up winning the race, extending his Drivers' Championship lead over Lewis Hamilton to 14 points, whilst Raikkonen took second to close the gap to Red Bull's Daniel Ricciardo to just a point.

Marchionne has now been speaking about the team line-up for the next campaign and he admits there is a strong possibility the current pairing will be kept on.

"It is more than 50% probable," he said. "They are great together so it would be a risk to change the game now. Let's see if we can keep them for 2018. I think they want to stay.

"We should be able to announce our drivers at Monza. Nothing is signed yet but we are talking to the drivers and the agreement may be close."
