Lazio are ready to part with Mauro Zarate but will consider a permanent deal and not a loan move, according to the forward's agent.
Giuseppe Bozzo says that the Italian club are willing to let the Argentine forward leave this summer but will enter negotiations for a bid of only €20million or more.
"I showed the proposal to Lazio president Claudio Lotito," Bozzo told the Italian media. "But he said the player will not leave the club on loan.
"They paid for Mauro over €21million and Lotito wants to get at least that amount."
Italian giants Inter Milan, who have recently sold striker Samuel Eto'o to ambitious Russian club Anzhi Makhachkala, are said to be interested in the 24-year-old but are willing to take the Argentine on board only on a season-long loan deal.
Zarate joined Lazio from Al-Sadd on a permanent contract in 2009 and despite showing early promise, has struggled to find consistency and has also fallen out with the Aquile coach Edy Reja. His contract with the Rome outfit runs until June 2014.
