Kimi Raikkonen says he will employ gut instinct to decide whose car he will be driving in 2014. Raikkonen, the 2007 champion, is the favourite to replace Mark Webber at Red Bull next year, in front of the Toro Rosso driver Daniel Ricciardo.

"There is going to be the overall package and whatever feels right for me," he said. "Whatever the decision will be might feel stupid to somebody else, it might just feel right for me.

"I have no idea what will happen, we have to wait and see what will come, but hopefully whatever it will be it will be the right choice.

"Basically everything has to feel right. In the end it comes down to whatever I think is the right one. There will be no guarantee the choice will be a good one in the long run but I am fine with whatever the outcome will be. You live with your choices."

Red Bull's team principal, Christian Horner, says he will choose Webber's replacement before the end of August. "We are homing in on our position and we will take the summer break to reflect on it and make a decision after that," he said.
