The opening match between Laos and Brunei provided a full reveal of the sleeve patch pairing for the inaugural FIFA-organized Southeast Asian tournament.
Moving away from the previously expected navy blue, the official tournament patches feature a clean white base. Most notably, the "Football Unites the World" sleeve patch on the left arm is the exact same design that made a single, exclusive appearance at the recent World Cup Final between Spain and Argentina.
Big thanks to @What The Kit for spotting and making the collage.
