Why Argentina can’t retire Messi's number 10 jersey

Lionel Messi confirmed his retirement from international football on August 31, 2026, following Argentina's loss to Spain in the 2026 World Cup final. Although the Argentina Football Association expressed a desire to retire the No. 10 jersey in his honor, FIFA regulations prevent national teams from permanently leaving squad numbers unused. Therefore, Argentina will need to assign the No. 10 jersey to another player, with Nico Paz and Lautaro Martinez being potential candidates.
