Crystal Palace target Jeroen Zoet is valued at €5m by his current club PSV, according to A Bola, via Sport Witness.
The report claims that Portuguese side Benfica are also interested in the shot-stopper and could be set to rival Palace.
Benfica are ready to switch their attentions to Zoet after they failed in an attempt to sign Lukas Hradecky from Eintracht Frankfurt.
They were unable to meet his €2m wage demands, with the report claiming that Palace do have a financial edge over Benfica.
Palace have been linked with a move for Zoet this summer as they look to strengthen their goalkeeping options.
Steve Mandanda signed for Marseille last month, leaving Wayne Hennessey with no real competition for his place.
Zoet played 37 games in all competitions last season, impressing scouts at Crystal Palace.
The 26-year-old has played 219 games for the Dutch side since graduating from the youth side in 2011.
