Earlier in the year, there were reports that Tau had fallen out with coach Marcel Kohler; it was claimed the attacker was unhappy after being overlooked in certain instances.
Kaizer Chiefs and Wydad Athletic Club were heavily linked with the experienced attacker but the deal did not materialize.
Recently, there were rumours that the Red Devils wanted to compensate Tau by paying him R4.5 million to terminate his current deal, but the player wants double the amount.
Apart from Chiefs, Zamalek have been severally linked with the Lion of Judah but midfielder Reda Abdel-Aal, who played for the latter, insists the South African is done.
