I know Zidane hasn't trust our young players lately but our backup players consistently getting injured don't help the situation either. Odrizola, Militao, Ode, Jovic all of them were injured multiple times throughout the season.
In ideal conditions backup players should be ready to step up whenever starting player is injured or suspended, that's how you make a impression and get more often into the team. Jovic would get more time if he didn't have covid when Benz was injured
Odrizola was mostly unavailable and Vasquez took his place. Militao was playing beginning of the season then he got covid and Zizou played Nacho instead. Then Zizou gave him a chance again, now he is injured.
