Lotus team boss Eric Boullier believes that his drivers will be fighting for podium finishes for the rest of the season.

Kimi Raikkonen finished third in last week's Singapore Grand Prix after Romain Grosjean qualified high up the grid only to have to retire with engine problems.

Boullier told Lotus's official website: "Singapore was a good illustration of what is possible for the team in final third of the year.

"Once more Kimi drove an exceptionally strong race – even without considering his back pain."

Lotus have yet to confirm a replacement for Raikkonen after the Finn opted to join Ferrari for next season.
