World champion Sebastian Vettel has no preference about which driver will replace the retiring Mark Webber at Red Bull next season, according to team principal, Christian Horner.

Red Bull will choose between the 2007 world champion, Kimi Raikkonen, and Daniel Ricciardo, a product of their young-driver development programme and currently with Toro Rosso.

"I don't think Sebastian has any concerns about going up against any driver, and he hasn't voiced a preference either way," said Horner.
