Sane has landed in Munich to complete a medical ahead of his £55million switch to Bayern.
BILD says he headed straight for the first part of his medical with a club doctor that lasted around three hours before going to his hotel just before midnight.
The 24-year-old will return to complete the final part of his medical today before an official announcement is made by both clubs.
Sane is expected to sign a five-year contract after the two clubs agreed a fee on Tuesday.
Bayern will pay £44.7m fee up front with a further £10.1m in add-ons, while City have negotiated a 10 per cent sell-on clause
Sane has agreed a bumper £20m contract - pocketing more than double what was on the table from his current employers, reports The Sun.
