The title put me off. I was expecting for Iruka to blabber something about his youth of whatever and for naruto to listen to him. But good news, it wasn't like that.
All I can say is : finally!
Sasuke should be up next, because I don't think it should be fair naruto going all out on zetsus and edo tensei shinobi and then sasuke comes fully healed and fights naruto. So we should have sasuke on the battlefield very soon.
The battle begins now.
