Pisa president Giuseppe Corrado admits major interest is arriving for Lorenzo Lucca.
The Italy U21 striker is being linked with Inter Milan and Juventus.
“Every day we listen to calls and messages, our availability is great," Corrado said of Lucca.
“It's normal that such a talented boy is coveted, but has yet to complete his growth. But sooner or later we will have to consider the interest of other clubs."
Lucca, who joined in the summer from Palermo, has six goals in seven appearances to take him top of the Serie B scoring charts.
