AC Milan's teenage goalkeeper Gianluigi Donnarumma is 'priceless', chief executive Adriano Galliani has warned.
Barcelona are among the clubs reported to be interested in signing the 17-year-old, who became Milan's first-choice goalkeeper earlier this season.
Donnarumma kept a clean sheet as Milan maintained their fine form with a 1-0 Serie A win against Torino on Saturday and Galliani insisted the club is not looking to sell the goalkeeper.
"Does Donnarumma have a price-tag? No," he told Mediaset Premium.
"There are these rumours about Barcelona, but he is our goalkeeper and we are really counting on Gigio.
"Nobody else in Europe has a regular starting goalkeeper this young.
"I saw Gigi Buffon on his debut, he was older than Gigio and there's a lot of work to be done before he reaches his level, but he does have great potential."
