The spending of other clubs is far from irrelevant. Liverpool don't compete for the top 4 in a vaccum. They are competing against other clubs with far more money to spend on their squad. "Without Ozil and Sanchez", why are we taking them out? Just like you tried to take out Liverpool finishing 2nd last year. This stuff happened. It can't just be ignored.
Giving 4th a go is not on unfair target, agreed. But finishing 5th certainly isn't cause for a sacking. That would be monumentally foolish. It's crazy to me that you are already passing judgment on Origi. Do you watch a lot of Lille matches? The kid is 19 years old and hasn't played a minute for Liverpool thus far. You cannot pass judgment on him yet. It's as simple as that.
This is Rodgers third season, not his fourth. He will be on thin ice is not all you've said. We had an exchange over him a few months ago as well. You seem to have a keen interest in downplaying his ability and accomplishments. He's not been brilliant obviously. But last season was pretty great and he's shown a lot of promise for them. There's no reason smart management would tie his future to finishing top 4. Another year of 5th place and developing the youth they bought into first team regulars would be promising.
The other clubs don't have "far" more money to spend though, as evidenced by Arsenal having a net spend of just £7 million more even though Liverpool received £75 million for one player. I took Ozil and Sanchez out because Arsenal's net spend is similar to Liverpool's, yet they spent it on quality for the first team that you keep insisting Liverpool cannot afford for themselves. By all accounts they apparently offered Sanchez more money than Arsenal did, he just chose Arsenal. If it's not an issue of affording players, then it becomes an issue of not being able to attract the top caliber of player. The problem then is that they've been top quality fees for lower quality players.
Liverpool finishing 2nd last season is a separate issue. It was a great achievement, but a very lucky one. To say otherwise is to ignore the context that you appear to love so much. I don't feel that you can take Liverpool finishing 2nd last season as a serious measure of Rodgers' quality as a manager, whilst simultaneously stating that 5th-7th is about their level and he's doing a fine job if he finishes there. Either he's good enough to have them up at the top, or his level is that rung just below.
I know this is Rodgers' third season. I referenced the fourth because I've been repeatedly talking about the end of next season as a time when his job will be under pressure, and next season will be his fourth. It's possible, though I feel unlikely, that Liverpool can catch up and make a proper go of top 4 this season, whilst creating a bit of a gap between them and Spurs/Southampton. It's also possible that everything clicks into place next season and they make a proper go of it then. I'm not saying that they should sack him if they narrowly miss out on 4th, I'm saying his job will be in danger if they finish a good number of points off this season (which is looking likely), and do the same again next season. Signs of progress will be fine, but I've not been at all convinced by his signings or his naive tactical approach to big games.
And as I've said, it's highly unlikely that even most of those young signings actually come to fruition. It rarely happens, and young players tend to need experience alongside them to help them develop.
As a somewhat separate issue, I think he's got away with a lot because of the entertaining football he's had Liverpool playing at times, particularly last season. As we've agreed, they punched above their weight massively last season, and it would have been unfair to expect them to mount a serious title challenge this season. If we accept that his first season was about par for the course, last season was an over-achievement, I think finishing >6 points off top 4 this season would represent underachievement. I also think that they should expect a season-long challenge for top 4 next season, and not find themselves in need of a November-March unbeaten run to claw themselves back up from 12th.
Issues that I think have been completely glossed over are:
Letting Suarez go - Clearly he's a despicable human being, but he was probably the best player in the league last season. He'd just signed a contract that would have kept him at Anfield until 2018 so it wasn't as if there was an urgent need to cash-in before his contract expired. Having no proper replacement lined up (or believing Adam Lallana and Rickie Lambert were adequate replacements) was a serious error. Considering Sanchez moved to Arsenal the same day Suarez moved to Barca, it very much appears like the two deals were connected. Liverpool should have ensured Sanchez was coming to Anfield, or Suarez wasn't going to Camp Nou.
Not actually building any strength in depth - Rodgers' line over the summer was that they were buying players for the starting eleven and not just padding the squad out with mediocrity. Everyone was in agreement that this was a great idea, especially given the extra games they'd have to play during their return to the European stage. It should have also ensured that the quality of the squad improved. The problem is that Rodgers categorically failed to provide this.
The main area for improvement identified at the close of the 2013/14 season was the defense, with Suarez's departure making another attacker the second priority. Lovren, Manquillo and Moreno were the new defensive additions, but Flanagan's season long injury, and the departures of Cissokho and Agger meant there was no more depth than the season before. Lovren's been kept out of the centre-back position by a 21 year old midfielder, Manquillo is finding himself behind a 20 year old attacker as an option at wing-back, and Moreno, the only defensive signing that plays with any regularity, seems to struggle with the actual defending part of the job.
As for replacing Suarez, that's just been a shambles. Lallana and Markovic are pretty much just rotation options, Lambert was apparently signed to be 6th choice, and Balotelli has been a laughing stock. Despite the key striker, Sturridge, making just 7 league starts this campaign, Balotelli has managed just 8, Lambert just 5, and Borini just 3. Rodgers apparently didn't want Balotelli, but without him that's another 8 starts and a further 6 substitute appearances going to Lambert and Borini.
The midfield clearly hasn't been strengthened because the only central midfielder they bought is currently their 3rd choice centre-back.
Actually being tactically inept - One of Rodgers' greatest strengths is apparently his astute tactical awareness. Frankly, this is a load of shit. It's all well and good finding a single tactic that works for a bit, but he's awful at adapting when it's needed. We saw it at the end of last season when they were eventually found out, and we've seen it over their last few games. Almost found out against Swansea, found out against United, and found out against Arsenal.
That's not the only issue with his apparent tactical ability though. He went into this transfer window with seemingly no idea what he was going to do with the team, despite it being his 3rd season in charge. Yes he lost Suarez, but he also spent over £100 million on new players with apparently no system in mind to actually play them in. He switched his tactic mid-season because it simply wasn't working (and it took him until November to notice), and he's now 3 games in to his latest incarnation being found out. He's got midfielders playing central defense, wingers playing wing-back, and wingers and attacking midfielders playing as strikers.
He's great at talking about how his team plays "the right way" whatever that is, and he does manage to get them playing some entertaining football at times (although this is aided by the comical defending), but playing some pretty football doesn't make him a tactical genius, especially not when he refuses to try anything different even when he knows it's probably not going to work.
