The controversy surrounding the Red Bull team showed little sign of abating last week.

Hans Stuck, the former F1 driver who is now Volkswagen’s motorsport representative, called on Dietrich Mateschitz to replace both his personal racing advisor Helmut Marko and Red Bull team principal Christian Horner with the Scuderia Toro Rosso team principal Franz Tost.

“What the team management did in Britain was an absolute outrage,” Stuck was reported as saying in his column for the TZ newspaper. “Whoever decided to take the new wing away from Webber qualified for his final pension.

“Christian Horner is just a puppet – the strings for Red Bullboss Dietrich Mateschitz are pulled solely by Marko. Mateschitz must respond by putting in a new man at Red Bull; Tost is in every respect one of the best managers in F1."

By any standards this is strong stuff from Stuck who drove for March and Brabham during his F1 career during the 1970s and also gained a reputation as one of the sport’s most accomplished sports car drivers.

His intervention in this increasingly vexed matter will hardly help RBR’s efforts to draw a line under the controversy, even though Mark Webber did last week concede that perhaps, on reflection, he went public a little too much on the subject of the Silverstone spat.
