The Bavarians have done a lot of transfer dealings this summer having signed the likes of Sadio Mane and Ryan Gravenberch.
The German champions are also keeping one eye on the future after completing the signing of three brothers from Mainz 05 - including a nine-year-old.
Aristide (14), Aviel (12) and Alex (9) Hentcho Nseke have officialy joined the club, while their father has also been given a coaching job.
The family were contacted by Bayern last autumn and the deal is said to have been completed in June.
Bayern's youth boss Jochen Sauer defended the move, telling Bild-am-Sonntag that the club were mainly interested in the eldest of the trio, Aristide.
He said: "After our scouting department contacted the parents about Aristide, the family emphasized that a change would only be considered if the entire family moved to Munich or switched to FCB."
Sauer continued: "Mainz was informed at the beginning of the talks and was always involved. Together we have also agreed on a corresponding training allowance. Everything between the clubs was very professional.
He later added: "From a sporting point of view, the change of the U15 player Aristide was first on our agenda."
The youngest of the three brothers, Alex, has had his football videos shared by the family on social media, with the clips garnering thousands of views on TikTok. Little Alex also has 20,000 followers on the platform.
All three brothers are already under contract with Nike. For the two siblings, that's faster than Lionel Messi who got his first kit supplier contract at the age of 14.
