The difference between the two versions of the jersey are the shoulder patches and the font used for the player name and number. UCL Patches are worn during the competition and PL patches are worn during the 38 match games. The Premier League patches are made by Uni-Sport and are a vinyl/plastic material. We carry the same size/style that the players wear on the pitch. For the Champions League and Club World Cup patches they are made by Sporting iD and are a thicker felt style. Patches are applied with a heat press. Normal wear and tear can cause the patches to lift. This is not necessarily a quality issue as the rigid patch can be stretched if the jersey is stretched. For best results air dry your jersey as dryers tend to cause the most ruckus with the felt style patches.
