Former Barcelona academy chief Aureli Altimira is baffled by news Ansu Fati can be sold this summer.
The Spain international is being linked with Wolves and Manchester United amid talk he will be cashed in over the coming months.
Altimira told Marca: "It is unimaginable for all of us who have worked at the base that they want Ansu to leave. In no way.
"He is a top player, who makes the difference, has a lot of goals and you would have to pay a lot of money for a footballer like that.
"The problem is that the bar was set very high (early in his career)."
