On 5 July 2018, it was announced that Bauer was loaned to 1. FC Nürnberg for the 2018–19 season. Nürnberg secured an option to sign him permanently at the end of the season.[6][7]
In June 2019, upon his return from loan at Nürnberg, Bauer was released from training at Werder Bremen.[8]
On 20 August 2019, he signed a long-term contract with Russian club FC Arsenal Tula.[9]
Eligible to represent Germany or Kazakhstan, Bauer revealed that he had rejected an offer from the latter in February 2015 in hopes of representing Germany.[13] The next month, he received his first call-up to the Germany U20 side and represented them at the FIFA U-20 World Cup in New Zealand that summer.
