A match-worn shirt is a shirt that was worn by the players during the game. Unless otherwise indicated in the description, the shirts are offered unwashed.
A match-issued shirt refers to either a shirt prepared for a substitute who did not play or to a shirt prepared for a footballer who played but did not wear the shirt. The shirts may or may not have traces of use, as some players use them for warm-up sessions as well. Many footballers wear multiple shirts during a match.
A match-prepared shirts are prepared, but not for a specific match. They are, for example, a shirt prepared for a player who ended up not being in the starting team of a game.
Please note that worn and issued shirts may have traces of use, including marks, tears, or imperfections. You can refer to the product photos to see the condition of the shirt.
