Although he won the last race of the season at Interlagos and has one point in front of Lewis Hamilton, Kimi Raikkonen should wait if the championship title is his.

After Brazilian Grand Prix the stewards summoned representatives of BMW-Sauber and Williams for alleged technical irregularities.

Lewis Hamilton has finished the race on the seventh place, while Williams driver Nico Rosberg finished fourth and the BMWs of Robert Kubica and Nick Heidfeld fifth and sixth, respectively

In case the stewards will decide to disqualify the three drivers, them Hamilton will be prmoted to the fourth position and he will win the title.

According to the reports the stewards are investigating a fuel temperature irregularity.

Raikkonen, who had earlier in the season said that he thought that the championship was no longer a possibility, joked after the race that he had never said that.

"We certainly always believed that we can recover and even with the hard times we were sticking together. We reduced the gap and then we came from behind to not only take the constructors' championship, but also the drivers'."

"I had an ideal start and then I saw Hamilton slip off in my rearview mirror and then I knew that I must have a chance. But even after I won the race, I still had to wait for a long time before Lewis finished", Raikonnen added.

Hamilton’s bad performance was due to a gearbox malfunction suffered on lap eight, with the problem relegating him from sixth to 18th.

Alonso congratulated Raikkonen for winning the championship. "I always said that whoever had the most points on the last day of the season deserved the championship.

"I knew that Ferrari would manage a one-two finish, so I could just wait and see if something was going to happen to them to have a chance to win the championship."
