Speaking to Sky Sports after the match, the German manager said: "This one feels really, really rubbish. I need time to process that. I am standing here and to talk about this game is really tricky. Two different games I would say, with the first half and second half. The first half was absolutely not good enough so we showed a reaction. The reaction was we lost conviction from the last game. We tried to get rid of this but that worked out as much as we wanted. To concede that goal was a horrible goal to concede with a completely free player in the area. That cannot happen but it happens.
"Andy Robertson gets the other ball so it's like scoring a goal if you don't concede from that. Crystal Palace didn't have many more and we controlled it better and then second half we can easily say if we don't score with these chances what can you say? The game in the second half was much better, Trent coming on and at that moment the structure changed. We caused problems and we had big big chances. If we stand here and win the game 4-1 we could have seen the same game with a completely different result. But we didn't so we have to take that."
