The 20-year-old Singh, who joined Bayern in the summer from Wellington Phoenix in Australia's A-League, made his debut for the German champions when he was introduced for hat-trick scorer Philippe Coutinho.
Singh was named on the bench due to a personnel crisis which left the German champions without the likes of injured duo Kingsley Coman and Corentin Tolisso, and the suspended Javi Martinez.
Although he was given little chance to impress with the match already wrapped up, the New Zealander has been tipped for big things.
Having been on Munich's radar since the age of 11, Singh's performances for Wellington in the 2018-19 A-League season convinced the Bayern hierarchy to sign him.
Singh, an attacking midfielder in the mold of Mesut Ozil, is the second New Zealander to play in the Bundesliga after striker Wynton Rufer -- who carved out an eight-year career in the Bundesliga for Werder Bremen and Kaiserslautern between 1989 and 1997.
