Two goals for the hosts in the first-half set the tone for a disappointing defeat at Selhurst Park on Monday night.
Jean-Philippe Mateta headed the opener when we failed to deal with a deep free-kick and shortly afterwards Jordan Ayew curled home the second.
We improved after the break, going close through Emile Smith Rowe and Martin Odegaard before Odegaard felled Wilfried Zaha inside the area, and the Ivorian scored the penalty to seal the win.
Eddie Nketiah later hit the bar, but we were well beaten on the night.
