According to TotalRace, Red Bull Racing team adviser Dr. Helmut Marko wanted Mark Webber to retire already in 2011 and 2012, but owner Dietrich Mateschitz stepped in.
The Brazilian news source reports that Helmut Marko had a dodgy relationship with the Australian, attempting to fire him on numerous occasions in 2011 and 2012 respectively. Mark Webber was outshined by Sebastian Vettel in both seasons, and Marko wanted to replace him. But Dietrich Mateschitz had the final word and the Red Bull owner decided to extend Webber’s contract in the last 2 years.
Red Bull still haven’t decided who will accompany Sebastian Vettel next year. Latest rumors suggest that Helmut Marko is pushing for Ricciardo to get the seat, while team principal Christian Horner and technical director Adrian Newey want Kimi Raikkonen. No deal has been signed yet, according to Auto Motor und Sport.
Helmut Marko is currently on vacation, returning to Milton Keynes at the end of August to present the options to Dietrich Mateschitz. The Red Bull boss will then make a decision and an announcement after the Belgian Grand Prix.
