We all have problems with injuries, but that is basic part of every sport and this game too.
Game was apparently made according to FA Premierleague, how many is there teams which doesn't have problems with injuries? Can you farm and buy read packs in real life to heal player? Real high level teams have their own hospitals, suregons etc., but none of them can heal player immediately. Besides that, has anyone heard that some team sold heavy injured player right after injury?
I know you are frustrated, but sometimes we need to be less subjecitve/more objective
