Lazio president Claudio Lotito is confident keeping hold of Hernanes.
The midfielder is being linked with Manchester City.
"If the player asks us for a transfer then we will consider that request, but that hasn't happened yet," Lotito told the Gazzetta dello Sport.
"Ever since I came here, the squad has always been strengthened, but the paths in football are endless
"Then, when someone has asked to leave, such as Aleksandar Kolarov or Stephan Lichtsteiner, we've made them happy."
