Bayern were eager to sign Sane over the summer - before he suffered a knee injury in the Community Shield. The German giants, at that point, pulled back.
However, contact has been maintained between the two parties.
BILD says Sane's representative David Gardner has just met with agent Giovanni Branchini, who also acts as an advisor to Bayern.
The summit was held to assure Sane that Bayern remain keen - with Gardner also delivering an update on the player's rehab.
