Lazio president Claudio Lotito is adamant Mauro Zarate is not for sale and hopes the striker can become a club legend.
The former Birmingham City forward is a reported target of Juventus, but Lazio are pushing for European qualification in Serie A this season.
Lotito insists Zarate's future has never been in doubt and sees the 23-year-old as vital to the club's long-term plans.
"We have never put Zarate up for sale," Lotito said in a press conference. "He's part of the club's long-term heritage."
Meanwhile, Lotito admits his admiration for Sampdoria and former Tottenham full-back Reto Ziegler, but has been knocked back in his hopes to sign him.
He said of Ziegler: "He's a Sampdoria player, he's a Switzerland national team player, and it seems he's not for sale."
