However, the tournament format will not be as familiar to many fans as it already has its own nuances. In the Nations League, the top teams don't all advance to the finals as might be expected in a typical knockout competition. Instead, the group stages lead, via semi-finals, to a finals 'day' where the best teams emerge, making it more complicated than traditional tournaments that many fans are used to. The focus on a single match outcome adds a different intensity, especially for teams under pressure for results.
