I understand Leclerc is considered a mega talent but certainly Ferrari have to understand Vettel's psyche by now. If he (Vettel) is not favored then he simply cannot thrive. A driver pairing of RIC and LEC is stronger than VET and LEC. I understand Ferrari at the time may have thought to keep continuity for car development but honestly Ferrari know how to build a car, they should have signed RIC and dumped Vettel. Or at the very least paried RIC and VET for one year before deciding to boot VET.
I am convinced that 2019 will be VET's last season. When he is gone, who will Ferrari turn to then?
