De Sa is currently at Fons Luminis Secondary School in Diepkloof for a soccer coaching clinic, but his mind is also back in the office in Parktown.
"As far as I know nothing has happened but we do have a couple of possibilities," he tells KickOff.com.
Rumour has it that the TP Mazembe boss was spotted in Parktown today, which suggests the two clubs may do a deal for Rainford Kalaba. De Sa admits his interest in the player.
"Kalaba is one of the players that have been spoken about at Pirates for a long, long time," he says.
"He is a quality player and I'm sure we are not the only club that would like to have him," De Sa adds.
Pirates have also been linked with Ghanaian international defender Mohammed Awal, but Maritzburg United insisted recently that he is not going anywhere, at least for now.
