Inter Milan want to replace outgoing striker Samuel Eto'o with Mauro Zarate, according to the Argentinian's agent.
Eto'o is expected to complete his record-breaking move to Anzhi Makhachkala this week, which will leave the Nerazzurri with a huge void in their frontline.
Diego Forlan has been heavily linked with a move to the San Siro, but Zarate's agent Giuseppe Bozzo says the 2010 European champions are also interested in his client.
Lazio have admitted they would be willing to sell Zarate at the right price, thought to be around €20 million, though Bozzo said Inter have yet to make an official bid.
"Zarate is no ordinary player," Bozzo told Sport Italia. "He's an important one for president Claudio Lotito and the fans. Mauro is very attached to the Lazio shirt and he'll remain if no side demonstrates a concrete interest in his services.
"Now Inter have shown an interest in him and a decision will be taken calmly. The Inter offer was made to me and not Lotito. It's an option that could transform into a negotiation. However, it is obvious that the two clubs would have to sit down and talk about it."
A potential stumbling block could be Inter's reported desire for a loan arrangement, with Lazio determined to only accept a full sale.
Zarate, 24, scored nine Serie A goals last season to Eto'o's 21 strikes and the Lazio forward's scoring record has never been as impressive as the Cameroon superstar.
