Jupp Heynckes won the treble in his last season managing Bayern Munich.
Bayern Munich have officially appointed former manager and club legend Jupp Heynckes as Carlo Ancelotti's successor.
The 72-year-old, who begins his third permanent reign at the Allianz Arena, has penned a contract to replace the sacked Ancelotti at the helm - a deal that will keep him in charge until next June.
Given that Heynckes had already confirmed that he had received an offer to return to the dug out on Thursday, it seemed all but a formality that he would succeed Ancelotti, and Bayern confirmed as much on their website on Friday afternoon.
A statement from the club read: "Bayern Munich's board and Jupp Heynckes today agreed on a contract until 30 June 2018. Jupp Heynckes takes over from next Monday as the head coach of Bayern."
Speaking about Heynckes' return, Bayern CEO Karl-Heinz Rummenigge expressed his delight at bringing an old friend back to his main home.
Rummenigge said: "Between Jupp Heynckes and Bayern, there is a great deal of trust. We are very grateful to Jupp for being our new manager. He is the ideal coach for Bayern at the moment."
Heynckes himself added: "I would not have returned to any other club in the world, but FC Bayern is a love affair for me. I am looking forward to the task ahead."
Heynckes has amassed 312 matches in charge of Bayern across two previous managerial spells - and a brief tenure as interim boss - and led Die Roten to silverware success in each of his former two eras as Bayern manager.
His first - between July 1987 and October 1991 - saw Bayern secure two Bundesliga titles and two German Super Cups, but it is Heynckes' second spell at the helm that led to his greatest footballing achievement.
The former Real Madrid gaffer led Bayern to an unprecedented quadruple during the 2012/13 campaign as Heynckes secured the German top flight title, German Cup, German Super Cup and Champions League trophy in stunning style.
Heynckes has been without a managerial position since his departure from Bayern in June 2013 following that legendary season, and boasts an astonishing 70% win ratio from all of his spells in charge of the European heavyweight combined.
