Bayern Munich thrashed Freiburg 5-0 in manager Jupp Heynckes’ first game back in charge of the reigning champions.
Bayern sacked Carlo Ancelotti last month, four months after he guided them to the Bundesliga title, with Heynckes returning for his fourth spell as boss.
An own goal from Julian Schuster put Bayern in front early on, before Kingsley Coman headed in a second goal.
The hosts scored three second-half goals through Thiago Alcantara, Robert Lewandowski and Joshua Kimmich.
The result leaves Bayern second, two points behind leaders Borussia Dortmund, who entertain RB Leipzig in the late game on Saturday (17:30 BST).
German Heynckes, 72, has won the Bundesliga three times and the Champions League once during his previous three spells in charge of Bayern.
In 2013, he retired after leading the club to a Champions League, league and domestic cup treble, but he returned after Ancelotti’s dismissal and will be the club’s boss until the end of the season.
Bayern went ahead after eight minutes when Schuster steered David Alaba’s low cross into his own net, before Coman made it 2-0 with a diving header from 12 yards after Freiburg goalkeeper Alexander Schwolow parried Arjen Robben’s effort.
Alcantara’s low 25-yard strike made it 3-0 and Lewandowski was left unmarked in the penalty area to increase the lead further.
Kimmich completed the rout in injury-time, backheeling Coman’s low cross into the net.
