I don't think it is as bad as it seems (with the exception of our midfield). Defense will improve when Stones, Dias, Walker, Ake, Akanji are healthy. Gvardiol- Dias- Akanji- Walker is really good and physical enough to concede way less than now.
Our wingers are playing well. Savinho, Nunes, Doku and Jack have been decent and producing chances in general. Foden today was really good, and once he gets his rhythm, he'll be back.
The problem is Kovacic- Gundogan- Bernardo. When two of those play (even worse when all play), we simply cannot press like we used to do. They are slow so they never get on time, and once the press is beaten they are super slow going back. But right now is all we have (McAtee is just as slow, and O'Reilly maybe should get a chance). Right now it is what it is, but when we have a fit squad only Kovacic should be starting along Nunes/Grealish or anyone hat is physically competent and strong to do the pressing.
Honestly, to the people criticizing, we are still producing plenty of chances. Pep teams always press, it's just that we cannot do it with the players that are available right now.
Walker- Dias- Akanji - Gvardiol
Foden - Kovacic - Nunes/Grealish
Savinho- Haaland- Grealish/Nunes
What we cannot do is having Haaland, KDB, Doku, Bernardo, Gundogan, Kovacic at the same time (our 5 least physical players for pressing effectively). Even having more than 2 of those at the same time means getting exposed.
Doku is great for the last 30 min, KDB same. I don't like either Grealish/Nunes as midfielders, but it's the only way to get some physicality and be able to press again without getting exposed time after time. If this line up cannot press without getting exposed, then the season is over for us. And it's fine. We regroup and try better next season. But if this is the case, I want McAtee, O'Reilly, Pusey, Wright, Rico playing more minutes than KDB, Bernardo, Gundogan, Stones, Walker who are all gonna be gone next season or in 2 seasons.
