Rudiger said: “First of all I hope everybody stays healthy [when they are away], that’s the main thing, and then after we have to set our minds straight and go back on a winning run.
“We have to win against Crystal Palace, it won’t be an easy match but that’s the only way you can get back on track.”
He added: “Of course everyone is very disappointed. We had a very good month until this game. It was tough but every game in this league is tough.”
