Zarate has been linked with a move away from Lazio in recent weeks.
“We are in November and there are no problems. The market opens in January,” Zarate’s agent and brother, Sergio Zarate, told Lalaziosiamonoi.it.
“All players have highs and lows, but I am convinced Mauro has great potential and he will show that on the pitch.
“We have a contract with Lazio and at this moment we are not thinking of alternatives. Soon I will speak with Lazio and see how things stand.
“I don’t think there is a problem, Mauro loves the fans and he wants to remain at Lazio.”
