"Though it puzzles me why Pirates keep releasing their captains, but I believe Nkosinathi Sibisi would be a perfect replacement for Maela," Vilakazi told KickOff.
"But it was just a matter of time for Maela because they were no longer using him. But Nkosinathi Sibisi has grown, he has improved a lot.
"Look at how he has managed to guide the likes of Thabiso Sesane and all these other players who found him there at the club. Look at how Mbekezeli Mbokazi is doing under Sibisi's guidance. That shows Sibisi's qualities as a leader," added the Buccaneers' all-time top goal-scorer.
"Being a great leader or a captain of a club as big as Orlando Pirates it's something you must have within you. You can be in professional football for years but still lack leadership qualities.
"If Sibisi is unavailable, Sipho Chaine must take over the armband since he has also shown growth. Such players are every club's dream."
