Dalić: "Nismo se puno bavili danskom reprezentacijom ovih dana, znamo da su kvalitetna reprezentacija, ali mi smo za klasu bolji."
Translation: "We didn't scout Danish team lately, we know that they are a quality side, but we are better a better team."
These things can backfire quickly. A lot of times in the past Croats already looked at who they'll play in the quarter final/half final just to get beat in the round of 16 because of their arogance/cockiness/over confidence.
I remember in 2016, a lot of Croatia newspapers were like "Autocesta do polufinala: Portugal i Polska" (highway to the half final: Portugal and Poland) after Croatia won against Spain and finished first in the group. They underestimated Portugal thinking they are cleary the better side just to get defeated by a lucky, but heartly and disciplined Portugal side, which is somehow similar to Denmark in this year. Let's see if the Croats learned their lesson or if they're going to repeat their mistake all over again.
