AMSTERDAM (Reuters) - Stoke City defender Erik Pieters is among four players who missed out on the World Cup that were called up in a provisional 25-man squad for the Netherlands' two internationals next month, the Dutch football association KNVB said on Wednesday.

Pieters, Rafael van der Vaart, Gregory van der Wiel and goalkeeper Jeroen Zoet were all named in the first squad for new coach Guus Hiddink, who has taken over from Louis van Gaal.

Hiddink would reduce the squad at the end of next week before the friendly against Italy in Bari on Sept. 5 and the Euro 2016 qualifier against the Czech Republic in Prague four days later, the KNVB added.

Jonathan De Guzman and Terence Kongolo are dropped from the 23-man party that went to the World Cup in Brazil, where the Dutch finished third.

Earlier this month, Hiddink promised that he would not tinker with the core of the side Van Gaal had selected over the past two years.
