Ferrari has confirmed Fernando Alonso will be joining them for Renault in 2010.
The double world champion has been widely tipped over the past year to sign for the Maranello outfit and the deal was confirmed today in a statement.
Alonso has signed a three year deal and will replace Kimi Raikkonen, who is expected to move to McLaren. Felipe Massa will line up as his team mate, with Giancarlo Fisichella as reserve driver.
Ferrari team boss Stefano Domenicali said: "We are very proud to welcome to our team another winning driver, who has demonstrated his amazing talent by winning two World Championships in his career to date."
Speaking about Raikkonen, Domenicali said: "We wish to thank Kimi for everything he has done during his time with Ferrari.
"In his first year with us, he managed to win the drivers' title, thus making his contribution to Ferrari's history and he played a vital role in our taking of the constructors' title in 2007 and 2008.
"Even during a difficult season like this one, he has demonstrated his great talent, with several good results, including a great win in Spa and we are sure that we can share more good times together in the final three races of this season."
Raikkonen said: "With common consent, we have agreed to terminate the contract binding me to Ferrari to the end of 2010, one year ahead of schedule.
"I have always felt at home with everyone here and I will have many happy memories of my time with the team. I am very sad to be leaving a team with which I have spent three fantastic years."
Alonso has yet to comment on the move.
