SOUTH African Football Players' Union chief negotiator Cappy Matutoane has called on club owners to honour their contractual obligations to players.
Matutoane is reacting to the increasing complaints from players over unpaid salaries and signing-on fees. He said they have 13 such cases they still need to attend to.
"We will take these club owners to task. How do you explain a situation where a player goes three months without a salary? The practice is rife in the National First Division.
"We are calling on Safa to intensify the punitive sanctions, as is happening with Fifa whereby a club is (diallowed) for a year from signing any player," Matutoane said.
Nathi Lions top the list of clubs accused of owing players money, with three complaining, while Batau and Thanda Royal Zulu had two each.
The affected Lions players are Sipho Made, Thulasizwe Ndlovu and Phumulani Mhamha, while Batau's players are Azwindini Maphaha and Melusi Cebekhulu.
Those from Royal Zulu are Thabiso Rammile and Reason Chiloane.
Others are Jonas Mavimbela of Hanover Park, Albert Kometsi of Witbank Spurs, Thandisizwe Dondasher of United FC, Christopher Netshidzivhe of Black Leopards, Alois Ngwerume of Dynamos and Luvuyo Kelepu of Carara Kicks.
Leopards have since fired Netshidzivhe for disciplinary reasons.
