Dietrich Mateschitz has denied Red Bull could be set to lose more prominent members of the championship winning team.

Dietrich Mateschitz has denied Red Bull could be set to lose more prominent members of the championship winning team.

Ferrari announced this week that Red Bull's chief strategist Neil Martin, a 38-year-old Briton, has switched to the famous Maranello based team for 2011.

But Mateschitz, owner of the Red Bull brand and the Milton Keynes-based team, insists that Martin's defection is not the start of a larger exodus of staff tempted by lucrative offers.

"No!" the Austrian billionaire emphatically told Germany's Bild daily.

"We recently extended the contracts of our 50 most important people," revealed Mateschitz.

Bild suggested that Martin's switch might persuade 2010 world champion Sebastian Vettel to also consider moving to another team.

Mateschitz answered: "Sebastian knows very well what team he can count on for the future."
