Yeah it's the fans who make the multi millionaires put in shit performances!
We don't have a good squad at the moment, and it's distinctly lacking leadership and football intelligence. Hopefully that'll change, but since the end of January we've known what we've got, and that it can't change until the summer so moaning at the game won't fix anything.
So if the crowd are moaning every time we make a pass that retains possession, but isn't a Gerrard-esque 70 yard through ball leading to a 1 on 1, people get huffy and it rushes our players. You can even spot it happening when watching on the tele.
Now if we had Xabi Alonso in the middle, or just someone with his temperament, he would rise above all the noises and make the right decisions and ultimately shut the crowd up (though they rarely admit to just being plain wrong). Currently, we have players like Emre Can who almost need to have their decisions made for them every few minutes from the coaches. I don't mean to single him out, he (and Moreno) are just particularly obvious examples.
They start to rush when they feel encouraged to, and rushing makes their already poor decision making worse. So we go from playing the way Klopp has coached them, with a calm buildup (if a little slow at times), but requiring a slight tweak in intensity to playing like headless chickens delivering long balls to players who can't jump, crossing balls into empty boxes, shooting from 45 yards, trying to skin multiple people when a better pass is on etc. Obviously as this happens, the crowd show even more unrest and so it exacerbates things.
I'm not saying players and coaches are flawless, just saying that our supporters could make things easier. In the past ten years especially we've unfortunately transitioned from a team whose supporters can help them achieve more than expected on paper, to one whose supporters make the average/mundane more difficult than it needs to be, and make things that were otherwise simple a challenge
