I am not saying Schlottenbeck all is set for Bayern but the problem for Bayern is that their best CB, Niklas Süle, has so far refused to renew his contract which ends in summer 2022, Dayot Upamecano hasn't played so well in his first season. Bayern do have a good LCB in Lucas Hernandez, but Bayer have a knack for wanting top German talent. His contract ends in 2023.
Ben Brereton for sure could be a good Kane understudy. I am wondering if Luka Jović also could do a job as Kane's understudy. 2 seasons ago he was the big deal when he went to Real M. for €60m.
