Euro 2012 - Emanuelson misses out on Euros
Netherlands defenders Urby Emanuelson and Hedwiges Maduro were the most experienced casualties when coach Bert van Marwijk cut nine players from his provisional squad for a pre-Euro 2012 training camp in Switzerland.
Milan's Emanuelson was expected to be the main candidate to replace Erik Pieters, who will miss the finals with a foot injury. Valencia's Maduro only recently returned to fitness after tearing ankle ligaments on international duty in October.
However, Van Marwijk has kept 18-year-old defender Jetro Willems in the squad that will travel to Lausanne on Thursday to prepare for a friendly against Bayern Munich on May 22.
Bayern's Robben is preparing for the Champions League final against Chelsea on Saturday, Sporting's Schaars is getting ready for the Portuguese Cup final on May 20 and Barcelona's Afellay is training with his club for the Spanish Cup final on May 25.
The Dutch host Bulgaria on May 26, Slovakia four days later and Northern Ireland on June 2 in warm-up matches.
