Dos Santos, 23, currently at the Olympics, wants to return to Spain. He last week ruled out staying at White Hart Lane when his deal expires in 12 months.
Tottenham boss AVB said: "I am not sure what Gio's thought process was, coming out with a statement like that.
"The player is contracted to the club. We respect him and are counting on him to return to club duty.
"Then we will make a decision that is best for the club."
