PSV Eindhoven chief Mark van Bommel says they must fight to keep hold of Hirving Lozano this summer.
But Van Bommel insists PSV are under no pressure to sell Lozano - no matter what is offered.
"We can say no to €50m for Lozano," he told De Telegraaf.
During the World Cup, Lozano's father revealed: "There have been Barcelona approaches, but nothing is concrete at this moment.
"When the World Cup ends the situation will be clearer.
"It isn't decided if he stays with PSV or leaves and signs for another team."
