Lars Lukas Mai will make his Bayern Munich debut in Saturday's Bundesliga clash with Hannover at HDI Arena.
The 18-year-old defender has been included in the starting line-up as coach Jupp Heynckes rests several players ahead of Wednesday's Champions League semi-final first leg against Real Madrid.
Mai, captain of Bayern's Under-19 side this season, is the first player born in the year 2000 to make a league appearance for the senior team and is their sixth-youngest debutant in the top flight.
Only Roque Santa Cruz, Berkant Goktan, Gianluca Gaudino, Toni Kroos, David Alaba and Pierre-Emile Hojbjerg made their Bundesliga debuts for the club at a younger age.
