He would make this decision because of the reorganisation which is going on in the Italian team. The team already made several changes in the structure. Iñaki Rueda has taken on the role of Sporting Director and Ravin Jain has been promoted to the pit lane.
Binotto may miss several races
During the Baku GP, Binotto did not join the pit wall but instead spent the race in the garage. Enrico Cardile, the man in charge of the technical side, was also present. He is busy working on the 2022 car. Therefore, it would not be a surprise if Binotto skips the Styrian GP, as the focus is on next year.
Austria will probably not be the only Grand Prix without Mattia Binotto. Last year he also missed out on a trip to Turkey and Bahrain. He also skipped the last race in Abu Dhabi, but that was due to illness.
