Kimi Raikkonen has blamed the clutch in his Ferrari for his bad start to the Italian Grand Prix on Sunday.
The 35-year-old began the race second on the grid but fell into last place within seconds of the start.
However, Raikkonen insists that there was a problem with his clutch as he attempted to get off the grid.
"It went into anti-stall when I let the first clutch go," Raikkonen told reporters.
"As far I understand I did the correct thing, but we can see there's a problem with the second clutch. It was not in the correct place. I'm pretty sure I put it correct as always. I don't know.
"Whatever it was it triggered the anti-stall and after a few seconds I was in last place. I've not had anything like this before."
Raikkonen finished the race in fifth place.
