I have a clue and its very simple, and its happen in the whole world of football.
In Premier League the 20 teams have tons of money and you only can put in the pitch 11 players, so you can buy X star but other its also buying other star and you cant have all the stars because you cant put them in the pitch, so we are heading to a football where all the teams have superteams in term of stars or future stars, but you are not gonna know never if this season can be good or bad.
In addition all the players are supertop so its more like a chemistry between players than skills of them. What are the main diference between top coachs? How they manage the locker room.
Cohesion has always been one of the top factors of a team being successful or not. It's why United were absolutely terrible despite having world class players. Liverpool still have world class players, and I don't think they've lost that chemistry, but rather lost the motivation. I was just talking about it in the Fury vs Usyk thread, but as soon as you reach your goal, i.e Liverpool winning the Premier League, and Champions League you lose motivation. So, we could be seeing something similar here with the players at Liverpool. They aren't as motivated for success. This might pass, and I imagine it's also a combination of teams learning to play against us, and also aging players.
Klopp has always been the best man manager for me, even before he was at Liverpool. I remember saying to someone when we were rumoured to sign Klopp, I said something along the lines if we get him, it'll be our best signing ever, and I was absolutely spot on. The guys a gem, not perfect, but a damn good manager.
