At the climax of the battle, both Itachi and Sasuke run out of chakra. However, Sasuke reveals that his actions up until now were only a preparation for his final jutsu.
Maybe Itachi had sustained
serious damage even before the battle.
ربّما كان إيتاتشي قد تكبّد جراحاً بليغة
حتّى قبل أن تبدأ المعركة
Und dann dieses Husten. Vielleicht
war er schon vorher angeschlagen.
Puede que Itachi hubiera sufrido 
daños graves antes de la batalla.
Forse Itachi aveva già subito danni
prima del combattimento.
Talvez Itachi tivesse sofrido muitos 
danos mesmo antes da batalha.
Возможно, ещё до битвы
 здоровье Итати было подорвано.
