Ferrari has ended rumours about its F1 driver line-up by officially confirming the expected news that it has re-signed Kimi Raikkonen for the 2014 season.

Raikkonen, who won the championship title with the team back in 2007, has agreed a two-year deal that will see him join forces with double champion Fernando Alonso in arguably the strongest driver line-up on the grid.

The 33-year-old Finn will replace Felipe Massa, who confirmed on Tuesday evening that he would leave Ferrari at the end of the season.

Raikkonen previously drove for Ferrari from 2007 to 2009 and took nine of his 20 F1 wins to date during his spell with the Italian team.

Ironically, his time at Maranello came to an early end when agreement was reached to release him from his contract a year early to enable to Ferrari to bring in Alonso for the 2010 season, with Raikkonen walking away from the sport to spend two years in the World Rally Championship.

Having made his return to the grid last year with Lotus, Raikkonen impressed many with a consistent campaign that saw him finish third in the championship and has again been a front-runner throughout the 2013 campaign.

While Lotus was keen to try and keep hold of his services for another season, the lure of a return to Ferrari was enough to see Raikkonen elect to return to his former team, who will hope that a line-up of two former title winners will be the catalyst for a championship challenge.
