"The quality of Gerrard was outstanding, it was an excellent midfield performance and was something we could not match," said the Dutchman.
"We did not do too badly, we did not give away possession but our build-up play from the back let us down.
"We have dangerous players up front but if we do not get the ball to them properly, we will not score goals.
"A lot of our play was really sloppy, if you do that you do not create much up front.
"It would have been good to have won at Anfield, but playing away to Liverpool is very different to playing Galatasaray and Bordeaux on their own grounds.
"We know we have qualified, but we still want to end the group with a victory against Bordeaux in our last match. That would send us into the winter in good spirits."
