Vettel will be staying put, says Red Bull boss

Formula One world champion Sebastian Vettel has no agreement with Ferrari and will be staying at Red Bull for years to come, team boss Christian Horner said on Tuesday.

Horner told reporters ahead of this weekend's British Grand Prix at Silverstone that persistent speculation about the 24-year-old German's future was wide of the mark, even if it was unlikely to disappear.

"I have spoken with Sebastian about it and he's made it quite clear that he hasn't had any dialogue and hasn't signed anything with Ferrari. The rumor mill always will continue," he said.
