The 72-year-old is set to return for a fourth spell in charge of the current German champions, having led them to a Bundesliga, German Cup and Champions League treble in 2013.
Bayern dismissed Carlo Ancelotti last week following their 3-0 defeat by Paris Saint-Germain in the Champions League, with his assistant Willy Sagnol taking charge of team affairs. Julian Nagelsmann and Thomas Tuchel had been linked with the vacancy but Heynckes will be unveiled as the Italian’s successor, taking over until the end of the 2017-18 season.
Bayern are without a win in their last three matches in all competitions and are five points off the Bundesliga leaders Borussia Dortmund.
Following the 2013 treble Heynckes, who has also managed in Spain at Real Madrid and Athletic Bilbao, as well as in Portugal with Benfica, said: “I can assure you that I’m not going to coach again. I had a worthy farewell.”
