Jun.23 (GMM) A recurring rumour on the verge of the French grand prix at the weekend was that Sebastian Vettel's deal to move to Red Bull Racing in 2009 is now all but guaranteed.



Even the Milton-Keynes based team's boss, Christian Horner, is warming to the media's regular attempts for signs of confirmation.



German magazine Auto Motor und Sport quotes the Briton as saying switching Vettel, 20, from junior team Toro Rosso to the 'A' squad is a "possibility".



Horner added that Vettel is doing "a very good job" this season, amid suggestions that veteran David Coulthard would be the current Red Bull driver displaced by the young German's graduation.



"We always try to have the best possible driver pairing," Horner said.



He also ruled out suggestions that Vettel might tire of the Red Bull stable if he is not given the nod to move to the premier team in 2009.



"He would not be in the position (to do that)," Horner said. "He has a long term relationship with Red Bull."
