Red Bull team boss Christian Horner has insisted that Sebastian Vettel will not leave for Ferrari in 2014.
A report on Monday stated that the 25-year-old German has agreed a deal with Ferrari that will see him join them in two years' time depending on their results in the standings.
"Sebastian Vettel, without a shadow of doubt, will be part of the Red Bull Racing team in 2014," Horner told BBC Sport.
Vettel joined Red Bull in 2009 and won the world drivers' championship in 2010 and 2011.
