Lazio director Igli Tare insists Ciro Immobile is not for sale.
The striker has been linked with a move away this summer.
But Tare says: "We will build Lazio around Immobile because he has a long contract and is an important figure in this club.
"He's had an exceptional season, but the team played for and with him too.
“Lazio are in the Champions League after 13 years, now we are studying initiatives to bring the club even higher with Immobile a key figure."
