I have always envisioned a ‘fall from grace’ like this was possible because it’s commonplace in English football.
Go back through the history books and look at Champions and what has happened to them.
City alone:
1936-37 Champions… relegated in 1938.
1967-68 Champions… 13th in 1969.
2017-18 Champions with 100pts, 2018-19 Champions with 98pts with an incredibly tough title run-in… out of the title race in November and finished on 81pts in in 2019-20.
2020-21 we nearly did a treble, 2021-22 Champions with another incredibly tough title run-in, 2022-23 treble winners, 2023-24 four-in-a-row record breakers… and what we’re witnessing this season as a drop-off.
This drop-off should not be a surprise. Even if everyone had been fit, I’d imagine we’d have had a drop-off this season.
In just my lifetime there’s been:
Villa 1980-81 Champions… 11th (granted with a EC win) in 1982
Arsenal 1989-90 Champions… 9th in 1991, 13th in 1992
Leeds 1991-92 Champions… 17th in 1993
Blackburn 1994-95 Champions… 7th in 1996
Newcastle 1995-96 2nd and 1996-97 2nd… 13th in 1998
United 2012-13 Champions… 7th in 2014
Chelsea 2014-15 Champions… 10th in 2016
Leicester 2015-16 Champions… 12th in 2017
Chelsea 2016-17 Champions… 5th in 2018
Liverpool finished 2nd on 97pts and won the CL in 2018-19, won the PL with 99pts and a CL final in 2019-20… 3rd on just 69pts in 2021
Liverpool finished 2nd on 92pts and a CL final in 2021–22… finished 5th on 67pts in 2023.
What City are doing this season is completely normal in English football.
