This is a silly and childish argument that falls apart when you apply basic logic.They can all get injured at absolutely any moment.
It's a risk every moment a player is basically alive.
It's just fucking dumb to drop them, throw and throw a game.
You're on your own here. Even Ange himself alluded to playing the dross because it was the last game before the transfer window closed.
You can get struck by lightening and die but you still wear a seatbelt when driving.
Your house can get broken into but you still lock your doors and windows when you leave.
You could get injected with drugs at a club by someone stabbing the back of your neck with a syringe but you'd still prefer to not leave your drinks unattended.
and finally....
players can get injured at any time, but you still manage their playing time and intensity to cope with the season.
