its interesting that charles has signed a long-term contract around same time lewis has ditched a contract to the end of 26 with merc. The new head of mechanical engineering at ferrari was the guy responsible for Merc's very good tyre life / wet weather characteristics. There has also been a rumour going back a few months that vasseur may or may not have gotten Pierre Wache to join ferrari in the future. Also Simone Resta was expected to rejoin ferrari after his stint at haas but he left haas early.
If these engineers all end up joining ferrari, and they actualy dont screw up strategy / operationally, we could see them returning to the pinnacle
(Wache btw is the technical director at red bull / their main designer for the RB18/RB19/RB20). Simone Resta, whilst being Haas' main technical person, was the main designer for the 2017/2018/2019 ferraris
