F1 sponsor guru Zak Brown had been tipped for the role but was yesterday unveiled as an executive director at McLaren in "first step in the group's transition to a new and strengthened organisational structure".
With Brown now out of the running, attention has now turned to Ross Brawn and Wolff for perspective roles, although Ecclestone has denied anything for Brawn is on the table.
Meanwhile, Wolff has told the French daily Le Figaro that he is not interested in leading F1
"No, I do not dream about leading F1," he said. "I think it is much more difficult than the people who criticise Bernie think. Adapting the sport to a digital universe and generating income is very complex and I prefer if someone else fixes the problem."
"I have to keep my attention on the development of my team," Wolff added
