Sasuke got the Rinnegan because he received chakra directly from Hagoromo, which is whats needed to awaken the Rinnegan right?

The whole reason Madara got it is because he got Asura's chakra, but it took awhile for the chakras to mix and become Hagoromo's chakra.

Sasuke got some Hag chakra from the source. It's not that he has Asura chakra really. He has Hagoromo chakra. At least that's what I think.
