Apr.30 (GMM) Ferrari team boss Stefano Domenicali has rubbished speculation that Kimi Raikkonen could retire from formula one with a second consecutive world title.

The 28-year-old Finn and current championship leader's contract runs out at the end of 2009, and he is undecided about whether he will sign a new one.

1982 world champion Keke Rosberg said last weekend that he can imagine Raikkonen, who described his Barcelona victory as the most perfect of his entire career, retiring in the near future.

His now 9-point lead in the drivers' classification has even sparked some rumours that he might try to break his Ferrari contract and walk away from the cockpit as early as after November's Brazilian grand prix.

But even though Raikkonen consistently refuses to commit to formula one for the long haul, Domenicali said retirement rumours surrounding the Finn are "nonsense!".

"I have heard this rumour and there is not a gain of truth to it," he angrily told the Swiss publication Motorsport Aktuell.

"Kimi is motivated from head to toe and I know that he is not thinking of retiring," he added.
