Portugal suffered a defeat in their debut at a U-20 World Cup, losing against North Korea. The article describes the mission as practically impossible, suggesting that the Portuguese team faced a very difficult challenge in this competition.
However, the aftermath of the game was positive for Portugal. Despite the defeat, the Portuguese national team managed to put up a good fight against their opponents, demonstrating a performance that exceeded expectations given a team considered a favorite.
North Korea is described as the defending champions and pointed out as a case study in women's football. This reference suggests that the North Korean team has a notable history in the sport, which reinforces the difficulty of the challenge faced by Portugal.
The article's title, "Not even the most closed country has this many secrets," appears to be an ironic reference to North Korea, a country known for its isolation and lack of international transparency.
