The 28-year-old has criticized the national team's showing this summer, and has stressed that the players must not forget their mistakes if they wish to improve.Bayern Munich attacker Arjen Robben has blasted Netherlands' European Championship performance after Bert van Marwijk's side failed to progress from the group stage of Euro 2012.
The former Real Madrid player started each of Netherlands' group match defeats against Denmark, Germany and Portugal, as the team was eliminated from the competition without a single point.
The winger joined up with the national side for the first time following the poor performance in Poland and Ukraine, ahead of this week's friendly against Belgium, and had some strong words to say about the campaign.
"The Euros were a complete disaster, just one big drama - worthless," the player told De Telegraaf.
"Too many things happened that prevented us from having a good tournament. We will have to talk about the things that happened. We have to look forward, but we must not forget what happened, and where it went wrong in June."
When asked what exactly went wrong in Poland and Ukraine, Robben was not clear.
"I don't want to give away details, but it's clear that we need to talk with each other."
Netherlands plays its first match since Euro 2012 against Belgium on Aug. 15.
