Eric Boullier unsure why outgoing Lotus driver Kimi Raikkonen disclosed pay dispute

Lotus chief Eric Boullier has expressed his disappointment with Kimi Raikkonen after the Finn revealed that a payment dispute led to his decision to quit the team for Ferrari.

Although admitting Raikkonen's decision to leave at the end of the season was a "disappointment", he made clear the team would strive to show via their on-track results in 2014 that the Finn has made the wrong decision. "Two years ago nobody would gamble on Kimi and we did it. Obviously we would have loved to carry on this story because the last two years was a nice story between Lotus F1 Team and Kimi Raikkonen," the Frenchman added. "We would have loved to carry on but this is life and so now we have to bounce back and actually make sure he's going to regret to have left us."
