The Young Stopper is sought by former Parma coach Cristian Chivu at Inter, says La Gazzetta Dello Sport.
However, the Nerazzurri is confronted with competition from Liverpool, who wants to transport Leoni to England this summer.
Refusing with Ibrahima Konate to discuss new conditions, see the Reds Leoni as a direct replacement. The Konate deal is now within the last 12 months.
For their part, Parma is happy with an auction to follow its course and will sell it at a starting price of € 40 million. Inter has offered € 30 million so far.
