The UEFA Nations League is a very young tournament. The first match of this tournament was played in 2018. It was for the first ever season of the League of Nations that the Adidas presented this wonderful Adidas Nations League 2018/19.
As you can see, the first ever UEFA Nations League ball is based on Adidas Telstar 2018 construction. Both of these balls are composed of six flat octagonal pieces that are heat sealed in a special chamber. The outer layer of this ball is created using the “PSC-Texture” technology, which guarantees perfect control and excellent aerodynamics in any weather.
