Feyenoord coach Fred Rutten admits they're likely to lose players this summer.
Defensive trio Bruno Martins Indi, Stefan de Vrij and Daryl Janmaat are all expected to be sold after the World Cup.
Martins Indi is being linked with Manchester United, while Janmaat is wanted by Arsenal and Liverpool and De Vrij is also interesting the Reds and Tottenham.
"The reality is to say that one or two players here may soon no longer be so," Rutten told NUsport. "I think the average Feyenoord supporter knows this.
"We haven't lost anyone - yet. No official offers have arrived. But we are ready."
