Like I said, an incredibly bad faith argument. Injuries not being mentioned in every single post doesn't mean they aren't being taken into account.
At the start of the season the expectations were that we'd improve further, finish comfortably in the top four, reduce the gap between us and the top few teams, get through the CL group and go as far as we could until we faced one of the top teams, and move towards a playstyle that will stand us in good stead in the future.
Due to the injuries, nobody realistically had those expectations anymore. Those expectations dropped to being something along the lines of finishing in the top 6, get through the easy CL group (any further depended on what opposition we got), and still move towards a playstyle that will stand us in good stead in the future, albeit with it being made harder by the injuries. That was all completely doable.
Instead we finished 8th with a negative goal difference (being very lucky to finish that highly), got regularly outplayed by teams that had just as many if not more injuries at the time as well as teams in the relegation zone, finished last in an easy CL group, and had a playstyle all season that didn't make sense and got ripped apart by basically every team that even attempted to come at us, that will need to be changed dramatically again for any future success anyway.
You and many others seem to use 'injuries' as an excuse to completely rip up any and all expectations. Refusing to acknowledge that, even with the injuries, there were certain expectations that should and could have been met.
As for the injuries being worse in the middle of the season...as bad as our defensive injuries were all season, we always had at least two centrebacks fit. It was only the last few weeks of the season that it got so bad that we had to play Casemiro back there, and at the same time Bruno and Rashford also missed some of those games after being available all season previously (plus the usuals like Mount and Martial of course). That was worse than we'd had at any other point.
