Wow, didn't expect this to be honest.
A little background from a german perspective:
- Rangnick was coach of arguably the best Schalke 04 team ever
- Rangnick managed and built Hoffenheim from 3rd division to a 'Herbstmeisterschaft' (no. 1 in table during winter break)
- Rangnick managed and built Leipzig from lower divisions to what they are today
Of course he was backed up with a load of money in Hoffenheim and Leipzig (well, at least for german standards, not for you guys
) but he completely built the identiy of these clubs and established a style of play from the youth teams all the way up to the first team, built the scouting of players and also youth coaches around this style, etc. etc.
He and Hoffenheim were basically the predecessor of Klopps Dortmund side.
He isn't the biggest motivator and according to reports not always the most easy going guy, so i don't know where i would put him compared to Klopp, Tuchel, Flick or Nagelsmann, but there is no doubt that Rangnick is one of the biggest "football brains" in germany.
I didn't expect this at all and I'm really, really curious how this will work out. To be honest I would be surprised to see him and Ronaldo get along because Rangnicks style relies on everyone following the tactics and fast (Gegen-)pressing.
Do you think Ronaldo will follow these guidelines?
I know that for you he is obviously no big name but I can tell you that he is heavily respected in germany and many wonder, why he didn't have an even bigger career. Maybe he is comparable to Bielsa in that aspect.
Anyways if you trust Rangnick enough to let him reshape your whole club, i think you will be very, very happy in a few years.
