Jupp Heynckes is happy to have returned to Bayern Munich as coach.
Heynckes, who led the Bavarians to the only treble in the club's illustrious history, will take charge on Monday, leading the club until the end of the season.
The veteran boss declared "It's not a comeback. It is a friendship service.
"I would not have returned to any other club in the world. I've only done it because FC Bayern is an affair of the heart for me.
"My coaching team and I will now present everything that the team will present the fans soon again successful football. I am very much looking forward to this task."
Heynckes will be assisted by Peter Hermann - who leaves Fortuna Dusseldorf - and Hermann Gerland, sporting director of Bayern's youth academy.
"Between Jupp Heynckes and Bayern, there is a great deal of trust," said Bayern CEO Karl-Heinz Rummenigge. "We are very grateful to Jupp. He is the ideal coach for Bayern at the moment."
The club's sporting director, Hasan Salihamidzic, added: "We're convinced that [Heynckes] is the right man to lead the team back to success this season and to reach our goals."
