Formula 1 team Williams have reportedly opened up talks that would see former champion Kimi Raikkonen return to the sport.

The 32-year-old Finnish driver, who won the world title in 2007 while racing with Ferrari, has recently been competing on the rally driving circuit.

However, Raikkonen is said to be eager to move back to Formula 1 and Williams shareholder Christian Wolff has revealed that discussions between the two parties are ongoing.

"Yes it's true we're in talks with Kimi Raikkonen," said Wolff. "This isn't a publicity stunt we're having very serious discussions."

Raikkonen quit Formula 1 in 2009.
