Talking about charisma, this man had it all when he came to the PL 2004 and revolutionized that Chelsea team. What a transformation we are now witnessing. He seems to have lost it in every aspect. He's become toxic and almost unemployable. There is no way he will get those players performing for him. They were a shambles at Anfield last night. I'm guessing half the team don't even want to play for him. Levy's got the monkey on his back!
A lot of things changed: even though his training framework is used by all top managers (Tactical Periodization), none of them use it to the extreme as Mourinho uses it. Manager like Klopp and Guardiola assimilated a lot of things from periodization, but they don't follow it as a religion.
Then there is the know it all atittude that makes him a liability if the conditions are not as he imagined. And the main issue: leadership. At 2000-10s, players were very different: most of them behaved like grown up childs, trying to skip training, sneaking out at party clubs, etc, so the leadership at that time should be tough and very demanding.
Nowadays most of the players are extremely professional, the grassroots teaching is 100 times better and football science has grown exponentially (look how Dortmund training facilities influentiated training centers all over the world). Passion for the game itself is not enough anymore, and he keeps palying that card to the players as if it was a puzzle solver.
