Bottom post of the previous page:
Autosport's logical conclusion to the scenario would be that IF Vettel gets a one-race ban, Ferrari should call on Giovanazzi to replace him in that race. Which would seem rather unlikely given the fact that Kimi is still way ahead on points, experience, knows the team and I'm guessing that the 2019 Ferrari isn't night and day compared to the 2018 car that he drove last year. Granted Leclerc isn't racing for the championship, but I'd say that Kimi is a way more solid partner to have in a tight race situation than Giovanazzi is.
But sure, an Italian driver in an Italian car might be hard for the team to turn down. That, as well as the fact that Kimi's career is nearing it's end and they'd want to give their junior driver a punt, are the only reasons I can think of.
