Agree but defence tend to get disorganized once you replace one of its elements towards the end of the game, especially when the pressure is too high. We have experienced that many times in the past and it always backfired.
while we keep making excuses like the lack of quality at the bench (which isn't true) others just grind through their way to the semis despite all obstacles.
wait wait.. Was Thuram unhappy about Acerbi? No, he just said that Acerbi should be with the club so that he could defend himself and explain what had happened. That it wasn't right time to go to the national team. I don't see anything wrong here unless I'm missing something.
