Has anyone read Das Reboot by Raphael Honigstein?
I read it a couple of years ago and it is fascinating. It's about the "reboot" that the German DFB did after the failure of the 2004 Euro's and how they (Klinsmann) completely reformed the way academies, training, and scouting was done in order to get a good team for 2006 for when Germany hosted the World Cup. Ultimately leading to the win in 2014.
It goes pretty deep at how the Bundesliga and DFB was set up and how this change brought about a revamped and exciting Bundesliga and national team. Easy and good read so far. It was written in 2015 and brings up Flick, Tuchel, Low, Klinsmann, Klopp, and other notable names.
