Lazio president Claudio Lotito insists striker Mauro Zarate is not for sale.

The Argentine has been axed to the bench for today's clash with Bologna and been criticised by coach Edy Reja.

"There is no Zarate problem.

"He has never been for sale and is absolutely not for sale, because he is a treasure for Lazio in the very long term," assured President Lotito.
