Bayern Munich have appointed Willy Sagnol as their new assistant manager.
Sagnol, who has managerial experience with the France Under-21 side and Ligue 1 club Bordeaux, previously played for the Bundesliga giants, making 278 appearances for Bayern.
Ancelotti was keen to sign a coach who played for Bayern and who has managerial experience, while Sagnol also appeared for France's national team during his playing career.
Ancelotti added: "Both are true of Willy Sagnol. I am very much looking forward to working with him."
"Carlo Ancelotti, one of the world's best and most experienced coaches, has chosen me, is a great honour for me. I am happy to be able to work with his team and his side."
Sagnol said: "I am glad that I can return to Munich with my family."
Sagnol was successful as a player with Bayern, winning five Bundesliga titles after picking up a maiden championship in France with Monaco, and will fill the void left by Paul Clement, who left Germany to manage Premier League side Swansea, successfully helping the Welsh club avoid relegation.
He made 58 appearances for France during his career and was part of the side that finished second to Italy in the 2006 World Cup.
