Kimi Raikkonen says the Ferrari team members are heading into the 2015 Christmas period 'happier' than twelve months ago as he reflects on a vastly improved season for himself and the Scuderia.

Following a torrid return to the Maranello fold in 2014 as he struggled with the underpowered and unbalanced F14T package, former world champion Raikkonen enjoyed an upturn in fortunes in 2015 with a more competitive car beneath him.

Though he was still comprehensively out-performed by new team-mate Sebastian Vettel - finishing a mammoth 128 points behind the German -, Raikkonen says he is taking confidence from the positive atmosphere within the Ferrari team ahead of 2016.

"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. 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.

"For the Christmas everybody seems to be happier. Obviously a long season is finished and soon everybody gets some time off, there is a relaxed feeling."

Raikkonen's place in the Ferrari team had seemed under threat following a troubled first half of the season, before an extension of one year was confirmed in August. Even so, Raikkonen only notched up three podiums, compared with Vettel's three wins and 13 podiums.
