German team sporting director Waller was interviewed by the media and talked about Wilz's performance at Liverpool.
Volal said: "I watched several Liverpool games with him, and he had some incredible moments. He ran a lot on the court, sprinted a lot, and often came to deep positions."
"But he did not show the way he played in Leverkusen or the German national team in the past. He had to solve the problem in a few weeks or months."
"I know he was not the kind of player who was dejected after three pass mistakes, he wouldn't do that."
"He was not only a great player, he had a very good character. He would go all out from beginning to end, his running volume was incredible, he would succeed."
