PSV Eindhoven admitted that Memphis Depay will likely leave the club in the summer.
Depay has been linked with Manchester United and was a member of Louis van Gaal's Netherlands squad who finished third in last summer's World Cup.
The 19-goal top scorer in the Eredivisie has also attracted the attention of Manchester City while PSV said Tottenham made a €20 million bid for Depay last summer.
PSV director Marcel Brands told ANP: "The chances are very high that he leaves. If you see what clubs are enquiring about him, they really are the best in Europe.
"When I talk for PSV I would say he is not ready and should continue here for another year. But I am realistic and if I worked at a big European club, I'd buy him without question.
"With a heavy heart [we would let him go], because a great player and a great guy leaves. But we are also proud that a boy from the academy is going to make such a step."
