Rome, September 11 - Ferrari announced Wednesday that their Formula One team has reached a deal to bring back Finnish driver Kimi Raikkonen next season. Raikkonen, who won the 2007 drivers' world title with Ferrari before leaving the team in 2009, has agreed to sign a two-year contract. He will replace Felipe Massa and partner Fernando Alonso in an all-world-champion driver line-up. "I'm really happy to return to (Ferrari headquarters) Maranello after spending three fantastic years there," said Raikkonen, who is nicknamed Iceman for his taciturn nature and coolness behind the wheel. "I have lots of memories linking me to Ferrari and I've always carried them with me," added the 33-year-old, who currently competes for Lotus and is fourth in the drivers' standings. "I can't wait to work with Fernando, an extraordinary driver, to give the team the successes they deserve". Raikkonen won the title in his debut season at Ferrari after joining the Italian team in 2007 from McLaren to replace seven times-world champion Michael Schumacher. His level of performance declined after the championship-winning season, amid rumours drinking was affecting his work. He left Formula One after Ferrari let him go in 2009 and had stints in the world rally and NASCAR series. He returned to Formula One with Lotus last season and impressed, finishing fourth in the drivers' championship.
