The Dutch national team were left struggling for words following a visit to the former Nazi German concentration camp Auschwitz-Birkenau on Wednesday.
Coach Bert van Marwijk and captain Mark van Bommel seemed almost bemused by the experience when speaking about it following Dutch training in Poland.
"It's so difficult to describe that I won't try to do so," said Van Marwijk.

"I just wanted to go because I think it's part of your education. I wanted to see it with my own eyes because this may never happen again."
Van Bommel was almost blown away by the experience and had even more trouble expressing his sentiments.
"We (the players) spoke about it afterwards, it was very emotional and impressive," he said.
"You can say a lot of things (about it) but for me it was very impressive. In school you learn some things about World War II and Auschwitz but now I've seen it with my own eyes."
The Netherlands were not the only team to vist the memorial site on Wednesday with Italy also making the trip.
It is believed that 1.3 million people were killed by the Nazis at the concentration and extermination camp.
Around 90 percent of those were European Jews but there were also significant numbers of Poles, Roma, Sinti, Soviet prsoners of war and Jehovah's Witnesses killed at the camp.
