In 2000-200 1 season, Manchester United specially launched the golden out-of-print uniform to celebrate the centenary of the club, but it did not bring good luck to Manchester United. In the game against Arsenal in the middle of the season, Manchester United wore a golden shirt, but lost miserably. European clubs often introduce commemorative uniforms, one for commemoration and the other for fans' collection, but wearing them often does not bring good luck.
