What surprising is Copenhagen is really struggle, they once qualified for Champions League and can give a fight. They haven't win any single match, if it's continue, they will not able to qualify.
IIRC they're one of the teams in Pots 1 too. Their form in the league is not that impressive either. Based on stats alone it seems like they create many chances to score but their conversion ratio is too low. I think their defense in the league is quite okay since they have 1.16 xGA so far. But if we look at the Conference League table I think the numbers are quite fair[2]. They need to win and improve their goal-scoring ability as quickly as possible. It's not impossible considering how many teams above them have worse xGA which shows if they fight against clinical teams there's a chance they'd lose. CMIIW.
