The Dutchman made his debut in a 3-2 defeat to Eintracht Frankfurt - its third straight loss this season - and after playing his first 90 minutes with the Bundesliga struggler, he was able to put his finger on why it is where it is in the league.
"When you start a game like we did, then you can never win," he said.
"We were far too fearful to begin with.
"Complaining about it now gets us nowhere, we have got to work hard and intensively on ourselves."
"We fought our way back and that is positive," added the former Real Madrid and Tottenham Hotspur midfielder.
"We have just got to put the big chances we created away."
"We are denying ourselves victories by not taking our chances," he added on his club's website.
