A few of Bayern Munich's young stars have proved that musical careers after football are unlikely during singing performances for initiation to the first team ahead of the new Bundesliga season.
The entire first-team squad gathered for a lunch with players expected to get up on the stage and sing a song of their choice, with hilarious results.
World Cup-winning French defender Lucas Hernandez, who joined the Bundesliga champions in club-record €80 million (£68m/$90m) deal from Atletico Madrid, took on Ritchie Valens' 'La Bamba' to the delight of his teammates.
