Sampdoria president Massimo Ferrero insists Mikkel Damsgaard is not for sale.
The winger has been a revelation for Denmark at Euro 2020.
“I don't know how much he's worth right now because he is not for sale," Ferrero told GR Parlamento.
“I am keeping a tight hold of him and we'll help him to develop, because I want to make a healthy profit at the end of it.
“As far as I am concerned, he is worth somewhere between €30m and €50m. He has talent and he will go far."
