Sorry for the TLDR post/rant...it was more therapy for myself LOL!
Forget Klopp, Anfield and all fans just want see some progress, movement, energy/effort, and not look like junk at home against a reeling squad (that just got obliterated by NF's second string) for the umpteenth time. The booing was a culmination of a year's worth of awful, passionless football with a whopping 11 losses so far in the PL.
I mean they scored early and instead of taking that energy and momentum they just completely parked the bus (again) and get completely carved up, have another awful defensive lapse and it's immediately tied. Regardless of the injuries and terrible roster, there is no intent to attack, no build up, no movement, creativity, energy, or purpose. What are they trying to do? What's the plan? It's constantly side to side, go back and then lose the ball. Then Slot subs Rio, the one bright spot of the whole year (who hardly plays) and this game in particular. Than that was the final straw. Slot said he did it based on fitness, but he has lost all benefit of doubt and rightfully so. In extra time Mama couldn't even get an outlet pass going because all the players were done and just stood there. Twice!!
I do think there is a massive rebuild that fans are struggling with though. It's hard to cope with what was, but winning a title last year to this is too much, and understandably so. The regression of players (father time related or not) and play is just not acceptable.
This club has made some massive mistakes recently, but step one is changing managers. Slot has to go at this point. He simply can't come back next year (although he will most likely). He has lost the fanbase, I think a majority of the locker room, and is not capable of leading this club going forward for many reasons imo.
Not sure how they recover from their massive signing mistakes last year though. Frimpong ....why even sign him? What an awful fit. Kerkez? Meh at absolute best so far. Wirtz? Incredible player, but a massive disappointment this year minus a couple moments of brilliance. Slot has no idea how to unlock him. Isak, an absolute $$ killer and complete waste. May go down of one of the worst signings ever on an injury prone player. Going to cripple this club in actually getting the multiple quantity players we need. I get it's only year one, but there is zero improvement here on any of these guys throughout the year (besides the one good signing in Ekitike...and he fell back down to earth as well, along with some signs of laziness). Do they need a new coach/system or a different league or team? Don't know.
We obviously need a ton of signings too. Who and how? Players like Olise are in general not going to come here even if the financial realities allowed it. They aren't coming to this mess or probably even a new coach. And it looks like a ton of players could/will be leaving. Mac, Jones, Alisson, Robbo, Salah, Chiesa and others are leaving or could leave.
Anyways, we could all go on and on, but there are big, worrying future concerns here. Salah's latest interview hints at the standards dropping and other behind the scenes issues and why he wanted to leave (I get that it's best for all parties, but there seem to be red flags everywhere).
We will see, but there may be some lean times ahead. But at least take step one, fire the mgr that is completely lost instead of having to do it next year and delay the start of a path forward.
