Chelsea is the king in this league I didn't see other teams as competitors for Chelsea, maybe there is Fiorentina from Serie A but in my opinion they are still under Chelsea based on the level so as you said I wasn't surprised if Chelsea won with a lot of goals. Almost all of us agree that Chelsea will go to the final I didn't say Chelsea would win the trophy because unlucky day could come at any time. So far Chelsea have played 3 matches and they scored 16 goals and conceded 3 goals.
Chelsea is like playing in Championship League lol, they can easily destroy any teams without need their best eleven to play.
Fiorentina is underestimated the team they faced because De Gea didn't play, not surprising to see Fiorentina lose.
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.
