The official has held initial talks with Bert van Marwijk to discuss the failure in Poland and Ukraine, but admitted the coach will not lose his job as a result
Bert van Oostveen, head of the Royal Dutch Football Association (KNVB), has confirmed that an internal investigation into Netherlands' performance at Euro 2012 has begun.
Van Oostveen and national team coach Bert van Marwijk met last Thursday to discuss the championship, where Oranje lost all three group games for the first time in their 108-year history.
But the president, who has been in charge since 2008, was at pains to stress the process, and therefore their final decision, will not be rushed.
"We have had discussions with various people in and around the Dutch national team and the KNVB," Van Oostveen told De Telegraaf. "We will continue discussions next week as well.
"This evaluation is a process. Only when we know exactly what went wrong, and who is responsible, will we draw our conclusions.
"Netherlands play against Belgium on August 15 and, by then, everyone will know where they stand."
He concluded the interview by quashing rumours that the under-fire Van Marwijk will lose his job as a result of the calamitous tournament.
"We have a contract with the coach until 2016. It is our intention to continue with him, so that he can work with a renewed Dutch squad for Euro 2016 in France."
