I am curious how much credit Rene Maric gets behind the scenes as well, because Bayern look very well drilled. Either way, Kompany has clearly built a strong staff around him.
There is also an underappreciated difference between implementing a possession model with superior technicians versus trying to do it with a bottom-end squad under constant pressure.
For a club like Bayern, man-management is almost as important as tactics. You need to handle stars, pressure, media, board drama, everything. He looks built for that.
