The German midfielder has found it difficult to get past the 6-0 drubbing at the Etihad Stadium, and said that the squad is desperate to get rid of the "bad feeling" with a victory at White Hart Lane.
"It's hard to sleep," The Mirror quotes the 23-year-old as saying. "It's not like we just move on with it, it's hard – it's not easy for your head.
"Everyone is more motivated now to get a result and not have a nightmare like last Sunday. You feel disappointed but you have to bounce back. You have to think positive as it's a long season.
"I hope we make that bad feeling stop by getting a positive result. Everyone knows what happened last Sunday so we are trying to go at the other Manchester side with everything we have."
Spurs have gone three games without a win in the Premier League.
