Now they face Manchester United at Old Trafford on Saturday, a game Schlupp knows they must get something from.
Speaking about his own performance in the 1-0 loss, Schlupp said to Eagles TV:"I've been working hard behind the scenes to get fit to try and help the boys. But it wasn't the best result or performance we wanted but on a personal note it's good to be back fit.
"I knew it was going to be a difficult game, and it didn't go the way we wanted it to. And when the game is like that it is a bit difficult to get into the pace of it and get going. It was physical but we learn from these things and move on."
On the coming game, he said: "We want to put things right as soon as we can and that's [Manchester United away on Saturday] is our next opportunity so we are going to go there ready and try and cause them so problems and try and win the game of course."
