I don't disagree that the quality of players in our squad is not good enough to win top honours.
My issue is that I feel some people are making out that it was impossible for anyone to do any better with the players we've had at any point, and particularly Ten Hag.
I feel like Mourinho probably did about as well as he could with the players at his disposal until he imploded.
For me, every other manager could have done more with the players at their disposal. And our current one is doing horribly, not using the current squad nearly well enough at all so I've no reason to believe he'd succeed with better ones.
It was the same with Soskjaer, the counter attack was decent at times, but he couldn't do anything else with some pretty decent players and for me that was down to his limited ability as opposed to near a full squad of players being not good enough.
I think a good way to move forward is to find a manager who can make the most of what's available, we might not win things immediately but if we become hard to beat, improve the football and get better results this will naturally lead to better players being more keen to join.
At the moment we're just not going to be of any interest to the quality of players people want at the club, and punting half our current squad at once isn't going to change that.
I think we're talking marginal differences. Our squad, even at full strength, isn't close to those of City, Liverpool and Arsenal. When it's spent the season ravaged by injury, it really is no wonder that we've fallen even further adrift and other teams have managed to overtake us.
As for "punting half our current squad at once", that's more or less what we need to do to get back to the top in the time-frame people seem to expect it to happen. It's also what Klopp oversaw at Liverpool. As I posted earlier in the thread, it took three summers to turn Liverpool's squad into one that was predominantly "Klopp's". In 2018/19 (his third full season) 10 of the 16 players with the most starts were signed with Klopp in charge. An eleventh was an academy graduate that he promoted to the senior side. That number is 10 (or 11) of 14 when you consider overall league appearances.
On just signings, that would be the equivalent of expecting Ten Hag to challenge for the title (and win/challenge for the Champions League) next season with a squad predominantly consisting of around 10 of:
Malacia
Eriksen
Martinez
Casemiro
Antony
Mount
Evans
Onana
Hojlund
and whoever we may sign in the summer.
You can pretty much immediately discount Evans and Malacia as back-ups, and I think it's fair to similarly discount Eriksen (given his age, the fact he was a free-transfer, and his history of nearly dying on the pitch). That means we would need four signings in the summer to all come in and hit the ground running, and a dramatic improvement of form and fitness from a good chunk of the others compared to what we've seen this season.
This also ignores that those players weren't the only players brought in at Liverpool in that period. Discounting back-up goalkeepers (as I've done with Bayandir), they also brought in Karius, Klavan, Solanke and Oxlade-Chamberlain (and Grujic in January 2016) in that time frame. In fact, Caulker in his first January was the only loan signing they made until the emergency loan of Kabak in the January window of 2020/21, five years later, and Arthur last season. We've made six already.
Making the most of what's available means top four and nowhere near the title, which Ten Hag achieved last season and still has an outside shot at this season. It is all Klopp could manage at Liverpool until the rest of his squad came together. Not that I think Ten Hag is as good as Klopp, but first full season Klopp went over a month and 10 matches in which their only win was an FA Cup replay against Plymouth Argyle. Second full season Klopp had a run of one win in six, bookended by a 5-0 defeat to City and 4-1 defeat to Spurs. This was without the squad turmoil we've faced.
As reigning champions, with a foundation far stronger than ours has been this season, an injury crisis saw them go on a run of three wins in 14 matches, losing eight of them, having been beaten 7-2 by Dean Smith's Aston Villa earlier in the season. Hell, they finished fifth last season, despite no real extenuating circumstances.
I think we need to get rid of Ten Hag to have a clean slate under INEOS and remove any dark clouds that may be lingering from his time here, but the reality is that we're going to need a fairly large clear out (however long that takes) and an understanding that progress isn't necessarily always linear if we're going to get back to the top.
