The striker is being linked with Juventus.
"We have never received an offer for him and he has never told me that he wants to leave," Perez stated.
"It is not easy to leave if your club don't want to let you go. However, Juventus are a team who we have a friendship with.
"If they are interested then we can talk. I'll speak with the player on Sunday and then we'll make a decision.
"If he does leave then it won't be for economical reasons."
