Ajax lost their Champions League encounter 2-1 at Anfield.
Schreuder said, "In the first half we had a little difficulty in moving the ball, but when we got in place we managed it immediately.
"We played against a great team, Liverpool gave us more intensity and are ahead of us in terms of condition, it was a very different game from the one against Rangers because the Reds effect a pressure that has no equal.
"We are still in a phase of construction and development. I cannot say that the success of our opponents has been undeserved, at this level we must do everything with great effectiveness to bring home the result."
