Kimi Raikkonen says a combination of fuel saving and the knock-on failure to get his tyres up to temperature played their part in limiting him to a relatively anonymous run to sixth place in the Canadian Grand Prix.

The Finn started sixth and joined Ferrari team-mate Sebastian Vettel in pitting relatively early under the Virtual Safety Car as part of a pre-planned two-stop strategy, but ultimately struggled to maintain a forward momentum as he fought a rear-guard action for much of the day.

Evidently frustrated over the team radio at being told to save fuel as he struggled to keep Daniel Ricciardo and Valtteri Bottas behind him, Raikkonen says slowing down meant he struggled to get necessary heat in his tyres as a result.

"Not an easy one," he lamented. "We didn't have one of our best starts but we managed to keep our position. Out of the second corner there was a Mercedes in the middle of the road and later on a Red Bull, so it was a struggle.

"When I had to slow down to save fuel the tyres would cool down and then I struggled to make them work. I lost most of the race on that, trying to get the tyres to work.

"The last sector was the biggest issue because the tyres would lose temperature in the long straight and then I would struggle for a few corners, before the tyres would work well again."

Raikkonen went on to finish sixth, which drops him behind team-mate Vettel in the overall standings to fifth having second overall just two races earlier.
