Ahmed Yehia, Razak's agent, said, "Zamalek has not paid Razak and he is very angry.
"Razak right now has many offers and we will study all of them and then talk with Zamalek, who still owe him $80 000 from April.
"The French side Lille OSC want his services and if Zamalek can't pay him he will not stay in the Egyptian side."
Zamalek technical staff, on the other hand, said they will punish the player after he boycotted their camp.
The player is under contract with the Egyptian giant for two seasons.
