The midfielder will remain at Lazio for the forthcoming season, according to sporting director Igli Tare, who is happy with the current Biancocelesti squad
The Brazilian was one of the Biancocelesti's top performers last season in the Europa League, Serie A and the Coppa Italia, in which the side beat rivals Roma in the final.
With Paris Saint-Germain reported to be interested in the 28-year-old, Tare has revealed that the player is keen to remain at the Stadio Olimpico and says he is happy with the current squad that the capital-based club have assembled.
"Hernanes is not for sale," the Lazio chief told Il Messaggero. "As far as we are concerned, he has never been on the market.
"He wants to stay and we want him to remain to continue winning. Football is unpredictable, as everyone knows, but he will stay with us.
"We are very satisfied with the squad that we’ve put together. We are competitive in defence and attack, while I think we have one of the best midfields in Serie A. Now we also have players with experience like [Lucas] Biglia.
"Let’s just say we are happy with our current squad, then if a transfer opportunity comes along we will take it."
Along with ex-Anderlecht midfielder Lucas Biglia, Lazio have also brought on board Felipe Anderson from Santos since the summer transfer window opened.
