They are as one and it’s simply beautiful
It is hard not to like Iceland, they are descendants of Vikings after all
They have population of something around 330k people, and yet they managed to reach Euro 2016 and WC 2018, and on top of that they were smallest nation (population wise) to ever participate in WC. It is something that us Croats can relate too, as we are successful in various sports despite being "small nation".
Those that watched Iceland games probably noticed this awesome chant by their fans
