Daniel Farke said he wants his City side to keep more clean sheets despite having one of the best defensive records in the league.
The Norwich boss is happy with how his side are defending this season, but still thinks they can improve in that aspect of their game.
Farke said: “I got the feeling that last season we had a few problems at the beginning but then we were defensively pretty solid.
“There were perhaps three or four exceptions for the rest of the season where we had poor defensive behaviour.
“We are there with more consistency defensively [this season], but we can still improve the amount of goals we can concede.
