Yup as I said it will be a mess.
Sainz and Hamilton will give a hard time for the team but I guess in this case they can have penalties on their salary and they can be benched for the 3rd driver.
Ferrari should still have Giovinazzi under contract if things are really bad he will race over Sainz.
3rd driver means not on the race grid anymore. only as a test driver and reserve driver if the 2 main drivers lewis hamilton or Charles Leclerc are injured can only race on the grid again. if there is an offer from another team to be the main driver or on the science grid, he will definitely choose to leave ferarri.
