I know most of you guys believe that Madara indeed gave his eyes to Nagato. I'm referring to what the OLD MAN *Madara* said on this scene.. But, in my opinion.. i don't believe his referring to Nagato. Ooopss.. here me out first! 
As we can see, he said he "left his real eyes to someone else". So basically, we assumed that he is LITERALLY "no eyes" at all before he implanted a sharingan eye on his left eye. And we're seeing it already, he only has left eye on him. No one knows where did he get that left eye or to whom did he get it? But, If you guys really believed that it was Madara who gave Rinnegan to Nagato, then you're saying that Madara indeed plucked his own eyes and transplanted them on Nagato just like what he did to Izuna. Therefore, does it mean that, Nagato was born blind? or he's literally no eyes at all? And Madara transplanted his real eyes to Nagato?
This really puzzled me.
Because, as far as i'm concern you don't need to plucked your own eyes and implant them literally to someone else. I'm referring to Itachi having Shisui's power, Itachi giving his MS that he received from Shisui to Naruto, and Itachi giving power to Sasuke after their battle.
You will only need to plucked your own eyes or someone's eye and implant them on yourself or to someone else if you we're LITERALLY blind. I'm referring to Madara plucking Izuna's eyes and transplanted on himself due to the fact that Madara overused his MS resulting to blindness.
