Lazio chief Igli Tare knows fans are upset over the departure of Mauro Zarate.
Zarate signed for Inter Milan on transfer deadline day.
Tare remarked: "The fans are right, I understand them. However, Zarate has been transferred for the good of Lazio. He wanted to leave.
"Zarate's departure was not in our strategy, but there were problems during the ritiro [training camp]."
