I believe Bensebaini actually played more CB than L(W)B this season, albeit in a back three. And Can is far from ideal at CB, but when you want to rebuild basically all areas of the squad, you can't get it all right down to the 2nd CB backup all at once. A few weeks ago there were fairly concrete links to Schlager and Laimer. So the club seems to be looking at aggressive box to box players. One of the Austrians, Bellingham, Dahoud, Can and Reyna or Reus as attacking options wouldn't be a terrible range of midfield options.
Going by the most advanced rumors:
Kobel - Meunier, Süle, Schlotterbeck, Bensebaini - Dahoud - Bellingham, Schlager - Adeyemi, Haller, Malen
That's probably not a team that can challenge Bayern over an entire season, but I wouldn't want to play against it either, if Rose can get them to work as a unit.
