Kimi Raikkonen has said that there is an option for him to remain with Ferrari for an extra year.

The Finn rejoined Ferrari last season on a two-year deal and, after a difficult 2014, it was suggested that this year could be his last in the sport.

However, he has revealed that there is an option for him to stay for an extra season, but he insists that it depends on how he and the team get on this year.

He told reporters: "There is an option on the contract. It's up to me, up to the team to do a good job this year. If it goes badly and I don't sign it, then I don't sign it. It's not the end of the world.

"The aim is to do well and there are good signs. Everybody's happy and I'm sure we can do a good year and we will see what happens in the future. I don't worry about it. We will find out at some point."

Raikkonen is partnered by Sebastian Vettel this season.
