Lotus driver Kimi Raikkonen has admitted that last weekend's DNF has made it "very difficult" for him to win the drivers' championship this season.
After the result Raikkonen is now fourth in the championship on 134 points, 63 behind the leader and reigning champion Sebastian Vettel.
"Of course it hurt quite a bit, but there's nothing that we can change now," he told Sky Sports News.
"It's an unfortunate thing to end up not finishing the race and it doesn't help. We still have a chance but it's very difficult."
Fernando Alonso and Lewis Hamilton are the other two drivers ahead of Raikkonen.
