Kimi Raikkonen says that the atmosphere at Ferrari has improved following the outfit's improved performance in the 2015 campaign.
Ferrari endured a troubled 2014 season which led to the exits of several senior team figures, while Sebastian Vettel arrived in place of Fernando Alonso.
Raikkonen, who helped Ferrari to second in the standings, says the squad has to keep working in the same manner if it is to overhaul Mercedes.
"The year has finished and obviously for the next year people always expect more than the team did well this year, but it’s always different," he explained.
"There were some new people and the atmosphere overall has been very good in the team this year compared to the previous year and obviously that’s normal for us.
"Obviously we all know where we want to be as Ferrari, Ferrari wants to win and it will not be easy, I mean, there are a lot of strong teams and all of them have the same idea of winning races and championships.
"Obviously, having done better this year, we have more expectations for the next one, but we are here for winning races, to win championships, so we will give our 100% to try to bring back the championship for Ferrari, but it’s too early to say.
"We can do our best but we can’t control what the others do, so we have to keep working the same way, always improving, then we will see where we end up in the next year. There’s not point to start guessing, we have to wait until the winter tests and the first race."
