Niang, who impressed during Stellenbosch FC's run to the PSL Play-offs last term, recently penned a deal with Eagles that will run until the end of the season.
The towering Senegalese hitman was previously playing for Kongsvinger IL in what was his third spell with the Norwegian second division side
"Well, I just needed something new. I was supposed to come back to South Africa anyway and I said 'why not' to Eagles," Niang tells KickOff.com.
"Eagles were the appropriate club. I'm coming to help the team. The boss is such a nice person and I said why not. He told me that it is club that doesn't deserve to be where they are in the league in South Africa.
"So this is the reason why I came back... I've signed a contract of six months, which runs until the end of the season."
Durban tycoon Sbu Mpisane has seen little return for the money he has pumped into Eagles since buying the NFD status of Mpumalanga's Sivutsa Stars in 2014.
The ambitious Mpisane has recruited big-name players like Katlego Mphela in the past in a bid to gain promotion to the topflight, but the club is yet to mount a serious challenge.
Eagles, who have former Kaizer Chiefs striker David Zulu on their books, are 14th on the table with 19 points from as many games.
They next visit log leaders Highlands Park at Makhulong Stadium on Saturday.
The side has won three, lost three and drawn once since Serbian tactician Kosta Papic returned to the club in December at the expense of ex-Orlando Pirates MultiChoice Diski Challenge coach Zipho Dlangalala.
Papic is currently assisted by his compatriot Vladislav Heric.
