Real Madara referred to Nagato as a brat and referred to Onoki as a kid.
He can't be referring to "Nagato/Pein" for that will make Pein as old as Onoki.
Real Madara must be referring to "Tobi/Nagato", his apprentice. This "Tobi/Nagato" has to be from the Uchiha clan too.
Real Madara imbued Tobi/Nagato powers including the Rinnegan. His task was to revive his master.
Instead, Tobi had other plans, assumed the character of his master, Madara (Tobi became fake Madara), gave his Rinnegan powers to another person, also named Nagato of the Uzumaki clan. Now Nagato/Pein's task was to revive Tobi if he ever dies, but instead used the technique in reviving Konoha villagers.
Tobi, being a student of Madara, is also a powerful Ninja but not on the level of the Real Madara. He was also able to control the demon fox and lead akatsuki. But he lost his arm with his fight with Torune and lost his left eye with his fight with Konan.
Of course, Tobi, being closely related to the mysterious Zetsu, was able to grow off his arm instantly. Tobi does not seem to have Eternal Mangekyou Sharingan, for when he used Izanagi against Konan, it closed, and had to "retrieve" the Rinnegan eye from Pein. In contrast, the Real Madara "awakened" the Rinnegan.
The last manga discards the "splitting theory" that Madara splitted himself somehow when he died, since Kabuto referred to Tobi as fake, and the demon fox never sensed anything on Tobi that closely resembles the real Madara (no reference in manga or anime whatsoever)
