Mayambela was on the wanted list of Chippa United. Both teams had initially agreed on the player's deal but the player turned down the proposed move.
The midfielder is keen to work hard and fight for his place in the star-studded Bucs team.
According to our source in Bucs camp, the technical team met yesterday and agreed to keep 'Proffesor' as they still believe in his capabilities despite him seeing little action last season.
Mayambela will compete with Daine Klate, Aubrey Ngoma, Tlou Segolela, Sifiso Myeni, Njabulo Manqana and Khethokwakhe Masuku for the wing position at Pirates.
Bucs have already loaned out defender Lizo Mjembu and Cyril Mashego to the Chilli Boys.
