Countless problems... Where on earth do we start?
Firstly, Pep must take the much of the blame. He continues to start players that are simply out of form. Prime examples of this are Walker, Savinho & Bernardo. All three simply aren't playing anywhere near well enough to warrant consistent starts whilst the likes of Mcatee are sat on the bench. In fact, i wouldn't be surprised to see Mcatee follow what Cole Palmer did and ask to leave in January- If he can't get game time now he never will.
Forgetting Pep picking out of form players, what has really killed us is 2/3 years of generally poor recruitment/squad planning. On the squad planning issue, we have too many aging players that are shadows of their former self (Walker, Bernardo, Gundo, KDB to name a few) and we have gone from having several 'great' players to simply 'good' players. The difference is vast. Our squad is also laughably paper thin when you consider the sheer number of fixtures we have to contend with.
On the recruitment side, When you look at the calibre of players that have departed us in the last 3 years it is genuinely frightening... Laporte, Jesus, Palmer, Zinchenko, Sterling, Cancelo, Mahrez, Fernandinho, Alvarez... I could go on. When you look at who we have brought in during the time the above names have left only really Haaland and Gvardiol have been what you could deem a success. Most have flopped badly- Nunes and Kalvin Phillips being prime examples.
I have a great deal of sympathy for the following: Walker (Been a great servant but his legs have gone), Gundo (Same as Walker), KDB (Getting old now, Always injured and carrying a lot of timber these days), Rico (Top squad rotation player but not good enough to start consistently in a teams midfield that aspire to win titles).
The other lads in the squad don't really have any excuse. Grealish has let us down for two years now, Savinho isn't good enough, Foden not fulfilling his potential.
Big problems. Breaking the bank for Barella at Inter in January would be a start towards fixing some of these issues.
