The midfielder is the second player to be registered from Pirates' development academy after Tshepo Lephoko, who has since joined Golden Arrows on loan.
"He is a fighter with great character," says Palacios of Ntuli, who attended trials with FC Twente last year.
"He is very good at defending and attacking. He possesses good technique and has a decent shot on him. He is one for the future," 'Njenje' adds.
Ntuli joins the likes of Joseph Makhanya, Gift Leremi, Lebohang Mokoena and Benedict ‘Tso' Vilakazi, who were all promoted from the Pirates development.
"It's difficult to compare that group of players with 'Nana' and Lephoko because this is a new generation. But I believe both players can create their own success at Pirates," says Palacios.
"Nana arrived at Pirates when he was 12-years-old while Lephoko arrived when he was 13-years-old. They both grew up here and understand the culture of playing for Pirates.
"I am happy to see the efforts invested in the youth by the club over the past few years paying dividends again after the promotion of Senzo Meyiwa and Siboniso Gumede."
