Kimi Raikkonen says no changes to the Ferrari Formula 1 team's start procedures or his preparations are required despite his Italian Grand Prix startline plunge from second to the back.

The Finn recovered to fifth place at Monza, having been last by the time he got his car going from its front-row slot.

Asked if he had focused on starts in the simulator or done any different work leading up to this weekend's Singapore GP, Raikkonen replied: "It's not like we need to do something differently.

"It was a small, small problem with a big end result from it.

"We've been doing the same things for a long time and it just happened to go wrong this time.

"It's not like the new rules have changed anything. It could have happened last year or earlier this year."

He said it was still not entirely clear what had gone wrong.

"We were still on the anti-stall and I thought I did it all correct, apart from obviously a finger or the second paddle might have been - for whatever reason - in a bit of a wrong position," he said.

"It was a shame, obviously a bit disappointing. But after 200 metres I was in last place so when you look at that [fifth] isn't too bad.

"But obviously when you start in second place, it's not ideal. It happens."

Raikkonen's second place on the Monza grid was his best qualifying result since the 2013 Chinese GP.

Asked by AUTOSPORT if he felt anything in particular had changed at the last event to allow that breakthrough, Raikkonen replied: "No, we did the same things as normal.

"I don't see that we did something special and obviously everything worked well all weekend and we were ready.

"Most weekends we've been feeling good with the car and it's just the small details that are a bit trickier."
