Amorim would be a disaster. Way too rigid refused to move off his 343 when it was clear the United team wasn’t built for it at all, regardless of the time he asked for. And beyond that, he absolutely couldn’t handle the media and routinely threw players under the bus. That kind of person will fail for the exact same reasons at Milan.
Glasner is not an Allegri type manager, he is just pragmatic and willing to switch up the system a bit unlike a guy like Amorim. If you think he’s just a low block counter guy at his core I don’t know what to tell you. Also when people say he is the “safe choice” that means he has more experience in big leagues, playing in Europe with different clubs, used to his best players being sold and working with less, etc. NOT that he is an old school manager who will play the same outdated playing style no matter what. He is an ascending coach and looking to take the next step at a bigger club. Not a dinosaur who’s been around the block. Taking a random coach you know nothing about over Glasner because you think he’s Allegri 2.0 is entirely the wrong way to think about it. Jaissle is an interesting option too, just pointing out a lot of you have a totally off perception of Glasner.
