Heynckes was soon parachuted back in for a fourth stint at the helm, and it only took the record champions a month to get back on top - where they have been ever since.
Bayern Munich are Bundesliga champions yet again, as a 4-1 win over Augsburg on Saturday allowed them to round off a sixth record successive title win. But there were none of the customary beer showers.
The result leaves Bayern 20 points clear with five league games left and underlined their absolute dominance of the Bundesliga.
Bayern's Bavarian neighbours Augsburg, though, were out to spoil the party and took an early lead through a weird own-goal from defender Niklas Sule after 18 minutes. Since 2000, Bayern Munich won 12 titles but not once were they able to win it in front of their fans!
A fine save from Hitz denied Robben a second as Bayern looked to run riot, with Sebastian Rudy passing up a golden chance to net his first Bundesliga goal of the season.

Corentin Tolisso's header restored parity after 32 minutes, and Bayern took control when James Rodriguez slotted in following excellent build-up play from Joshua Kimmich and Juan Bernat. Sergio Cordova forced Jerome Boateng to lose possession and Sven Ulreich then saved the Venezuelan forward's shot before the ball rebounded off Niklas Suele's face into the goal.
Robben all but sealed the title for Bayern after the hour-mark when he fired inside the right post after James kept the ball in play.
Aaron Hunt scored a brilliant late goal for Hamburger SV to rekindle its hope of avoiding relegation with a 3-2 win over second-place Schalke.
26- Robert Lewandowski has arguably been the vital element for Bayern this season, scoring 26 times in the Bundesliga.
Hamburg suffered an early setback when Naldo appeared to score with his hand, but goals from Filip Kostic and Lewis Holby put the home side ahead before Guido Burgstaller's equalizer for Schalke.
The only exception was the 1-0 home victory over Hertha Berlin in the 2014/15 season.
