The 2007 FIA Formula 1 World Champion made a move from Ferrari to Sauber at the end of the season last year after having spent five years with the Scuderia from 2014 and three seasons beforehand from 2007 – 09.
He will be partnering Ferrari’s junior driver Antonio Giovinazzi for the team but is in good spirits after Sauber improved last season, moving from near the back of the field to contending the mid-field teams.
"We'll see once we start driving the new cars where we are roughly and then we go from there," said Raikkonen (sportsmole.co.uk).
"Obviously it's a different challenge but I enjoy that too. If you ask people there are lots of different opinions about how it's going to go, but we'll find out next year and do our best.”
"I think we have a good chance to do some great things. Where that's going to take us, who knows?"
The Finn stated that from his personal point of view a change in scene behind the track is something that he is looking forward to. Ferrari are a much bigger and political team in comparison to Sauber.
"It's a much smaller team than where I've been, but I'm really looking forward to it, it's going to be different in many ways but the aim is still the same -- do well in the races. I think it's more pure racing and less the other stuff.”
"Hopefully it will turn out to be good for both of us. I have a good feeling about it and I'm exciting to go there.”
