The duo called time on their playing careers in May, leaving the Bavarian giants with huge defensive and midfield voids to fill ahead of the new campaign.
Ancelotti was keen to give both an immediate return to football, though after seeing his offer rejected he instead turned to Willy Sagnol to join him as assistant manager at the Allianz Arena.
"I wanted an assistant who knew the club. I tried to convince Philipp Lahm before the end of the season, I also tried to convince Xabi Alonso. They refused," he told reporters.
"Willy suits perfectly, he has the right profile, he has been successful at Bordeaux, and he knows the players like [Kingsley] Coman or [Franck] Ribery, and he will improve our trainer team."
