Seems pretty obvious to me, that if you run a player into the ground e.g. playing 95 95 95 95 every few days, they will get an injury that forces them out for months.
Far better to play them less and play a "worse" player for parts of those games, so they don't get that drastic injury. There is always an option.
Frank had the option to play Paulhinha instead more often, he also had the option to not play the two of them together as much.
Unfortunately, another serious injury for him, the fact he never got back to the player he was pre-injury for Conte, and age, means we will probably move him on in summer.
