As a Pole who from time to time watches football matches of Poland I can tell you: "You know nothing!"
We have wooden players with no tactical plan ("let's just kick the ball as far away from our goal as we can"), everytime there is Cup or Euro the expectations are super high and then there is this disaster happening.
It seems we always play 3 matches: an opening match, a match of last chance and a match for honor. And then team packs up their things and go back to Poland.
If anything happened to Lewandowski we would be totally screwed. That's why he is so popular in Poland.
Next match will be better ;)
