Lazio president Claudio Lotito is inviting offers for striker Mauro Zarate.
The striker has been linked with a move away from the Olimpico for well over a year.
"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," said Lotito.
