Yes and no. The squad under him benefited enormously from Kovac’s preparatory work because he relied on an athletic and running team. Although it didn’t work under him, it was only through this that Flick was able to build his successful football.
I don’t see it that way at all. Shortly after he took office, the players across the board said that at least now everyone knew exactly what they had to do. And the crucial fitness for the CL march was created clearly and clearly and documented by many, many videos during the Corona break. This is exactly where they worked more professionally and efficiently than the competition; the fitness of the actual summer preparation (Kovac) or the first two months of the season (Kovac) really no longer played a role after the pandemic break of several months. This was not only due to Flick, but also to the very good work of the athletic trainers and physios, as well as the excellent implementation of personal responsibility by the players at the time. That’s where Flick comes into play again, as he created a good team spirit. Plus the support of all the Bayern legends (there are a lot of videos there too).
You simply worked excellently athletically during the break, gave the players a good homework plan (which they implemented extremely well) and created team spirit. Niko Kovac did exactly zero preparatory work that had anything to do with the title rush. Not tactically anyway, but not in terms of athleticism either. Due to the Corona break, the fitness level of all teams was reduced to practically zero. Everyone had to start almost from scratch, like in pre-season preparation, only without classic team preparation. Many teams have failed because of this, but not Bayern, on the contrary.
I find it almost cheeky to cobble together some kind of contribution for Kovac.
