Anyone saying Hoffenhiem was good under him needs their head checking. No, they weren't they just got promoted and that was it, they couldn't challenge in a bigger league, he left them and 5 to 6 years later they then managed a 4th and 3rd place finish, which was nothing to do with Rangnick and all to do with Julian Nagelsmann who is now funnily enough with Bayern as he's a quality coach and manager. So all Rangnick is good at is taking teams from lower leagues and promoting them. He never makes them into title contenders or even play decent football
