Jupp Heynckes hasn't made wholesale changes or introduced a revolutionary tactical system since replacing Carlo Ancelotti as head coach on 6 October 2017, but he has got Bayern Munich purring again.
The red machine have won all seven of their assignments under the crafty veteran tactician, conceding just three goals and plundering 17 in the process. Bayern have their mojo back.
Watch: Heynckes has got Bayern back on track in no time at all
"We're seeing a gradual improvement," Heynckes said modestly, after Bayern went four points clear at the top of the Bundesliga standings with a 3-1 win at Borussia Dortmund prior to the international break. "The intensity is a lot higher in training, but every house needs a firm foundation."
The results of Heynckes' back-to-basics philosophy are marked. Bayern have conceded only one goal in four Bundesliga outings on the 72-year-old’s watch, compared to seven in seven under Ancelotti and interim predecessor Willy Sagnol. Their average possession count is also up from 63 to 89 per cent, while they have seen a marginal improvement in the final third of 2.3 to 2.8 goals scored per game.
