Mabuya, who is an attack-minded right-back, has scored one goal and provided two assists for Richards Bay this season so far. Conversely, Mbuthuma has netted two goals for the KwaZulu-Natal club this term.
Mbuthuma has seen his outstanding performances catch the attention of Bafana Bafana Hugo Broos who has included him in his preliminary squad twice previously.
Biyela seems to be open to selling his two assets if enticing offers are presented to him by the two Soweto giants.
