Lazio could consider selling star striker Mauro Zarate if they receive a profitable offer.
Despite stating that he is happy at Stadio Olimpico, the Argentine has long been linked with a move to Italian rivals Juventus, who signed Stephan Lichtsteiner at the beginning of July.
Lazio have no intention of selling, but with Miroslav Klose having already arrived and Djibril Cisse another probable signing, they have options.
And president Claudio Lotito has admitted that he would be prepared to listen to approaches which would be beneficial to his club.
He said: "Zarate is not on the market, as far as I know. Clearly if an important offer arrives, then we'll consider it.
"After all, Stephan Lichtsteiner wasn't on the market until he asked to be sold to Juventus."
Serie A approved a rule change on Tuesday which allows clubs to bring in two non-European Union players a season instead of one, and Lotito admits this changes the transfer landscape.
"This extra option does favour us and gives Lazio the opportunity to perform other operations on the market," he said.
"I can certainly confirm our transfer strategy has not concluded yet."
