Goals: 1-0 Schuster o.g. (8'), 2-0 Coman (42'), 3-0 Thiago (63'), 4-0 Lewandowski (75'), 5-0 Kimmich (90+3')
With a line-up boasting a familiar feel to Heynckes' last spell in charge of Bayern, the Bavarians began exactly where they had left off under the veteran coach and took the lead early when Freiburg skipper Julian Schuster bundled David Alaba's low cross into his own net. Rejuvenated and moving the ball crisply through midfield, the hosts could have added to the lead but Arjen Robben and Javi Martinez both wasted presentable chances. At the other end, the visitors had opportunities of their own, but were made to regret Mike Frantz nodding wide from close range when Kingsley Coman doubled Bayern's advantage with a clever header before the break.
Bayern remained in the driving seat at the start of the second half, although failed to create any clear-cut chances to reward their dominance. Indeed, it took until the 63rd minute for the champions to cut loose, Thiago waltzing his way through the Freiburg midfield and placing his shot past Alexander Schwolow from the edge of the box, much to Heynckes' delight. The 72-year-old tactician had further reason for cheer soon after: Müller sent Robert Lewandowski one on one, who made no mistake from close range, before Joshua Kimmich's strike in the closing stages sealed a memorable return for Heynckes in the Bayern dugout.

Man of the match
Although not on the scoresheet, Müller underlined his worth to this Bayern side in everything he did. The attacking midfielder – a Heynckes favourite from his previous spell in charge – looked liberated, constantly ghosting between the Freiburg midfield and defence and teeing up Lewandowski for the hosts' fourth goal.
