Helmut Marko dismissed the idea of an upheaval at Red Bull after the death of founder Dietrich Mateschitz.
The same, however, cannot be said for sister team AlphaTauri. In the wake of a disappointing year in which the team finished ninth above only strugglers Williams, the Austrian hinted some changes could be made under the former owner's son Mark and new chief executive Oliver Mintzlaff.
The death of Mateschitz in October was a huge blow to everyone involved with Red Bull. He bought the failing Jaguar team at the back end of 2004 and provided the resources necessary for the team bearing the brand name of his energy drink company to become one of F1's most dominant forces.
