None of the clubs he left upgraded, ironically. Even his hiring proves the idea that sometimes it's not about who you fire, but who you hire afterwards. He inherited the same amount of criticism that Nagelsmann was getting, but the fact that he's getting the same amount of criticism doesn't look good as an upgrade. He's a toxic individual, a former Mainz keeper said his knowledge isn't questioned but on a personal level he's the worst person he ever met in football. That's a lot. The thing for Bayern is who do you hire? Xabi seems perfect but Liverpool will be all over him.
