Lazio president Claudio Lotito insists their best players are not for sale.
Hernanes, Senad Lulic, Antonio Candreva and Federico Marchetti have all been linked with moves away.
"Hernanes is not for sale,” insisted Lotito in the Corriere dello Sport.
“Leonardo did not call me and I have not received any offers, though it wouldn’t matter anyway because our ideas are clear on this matter.
“Lazio will not sell Hernanes and this is also true of other players. I am referring to Lulic, Candreva and Marchetti.
“Our only focus of the transfer market will be to reinforce the squad.”
