AmaZayoni have won just one, drawn four and lost five of their last 10 league matches since December 2014.
They suffered a 2-1 loss to Ajax Cape Town in their last league outing after taking the lead in that game.
As reported by Phakaaathi earlier, the Aces management was not happy with the team’s poor form that has seen AmaZayoni moving down to 13th on the log and have decided to sack Barker.
Aces are said to have appointed Jacob Sakala as the new coach, while Barker will reportedly take over the general manager’s role.
