Zamalek have since expressed their interest in Billiat ahead of the January Transfer Window.
Zamalek assistant coach Tarek Yehia said the White Knights will try and sign the 2015/16 PSL Player of the Season.
“Of course I wish to sign Khama Billiat for Zamalek,” Yehia told Stad Al-Hadaf.
"He is a great tactical player, who has a lot of individual skills too. We will certainly try to sign him," he continued.
"If Zamalek president, Mortada Mansour, is determined to sign a player, he will bring him whatever the temptations of the Gulf clubs,” he concluded.
Zamalek's Egyptian rivals Al Ahly are also said to be monitoring Billiat's situation at Sundowns.
