David Wagner: 'We deserved to lose'
Wagner's troops were no match for 'Die Schwarzgelben', who earned a 4-0 victory at an empty Signal Iduna Park as the Bundesliga restarted.
"It was a poor performance and we deserved to lose," Wagner said after the game added:
"We weren't brave enough today. We need to dust ourselves down and improve for next time."
In their next game, Schalke take on Augsburg at home next week.
