Netherlands coach Bert van Marwijk on Monday announced a bumper preliminary squad of 36 players for Euro 2012 in Poland and the Ukraine, which begins on June 8.
Van Marwijk will have to whittle the squad down to three goalkeepers and 20 outfield players by May 29.
The 36 players will participate in an initial training camp in Hoenderloo from May 14-15, according to a statement released by the Dutch Football Federation (KNVB).
"We've had intense discussions with the technical staff in order to come up with a squad composition that was as balanced as possible," said van Marwijk.
Barcelona forward Ibrahim Afellay was included despite having only returned to training in March after six months out due to ruptured ligaments in his left knee.
Van Marwijk has also summoned nine previously unselected players, including PSV Eindhoven defender Jetro Willems, 18, and 20-year-old Feyenoord defender Stefan de Vrij.
PSV Eindhoven left-back Erik Pieters announced his withdrawal from the squad on his Twitter account later on Wednesday, as he is yet to fully recover from a fractured right foot.
His place in the squad was taken by Alexander Buttner of Vitesse Arnhem.
Beaten finalists at the 2010 World Cup, where they lost 1-0 to Spain, the Netherlands cruised through Euro 2012 qualifying, winning nine of their 10 group games and scoring 37 goals in the process -- more than any other side.
