The 7-0 is more historically significant and what sticks in your mind as a fan, not disputing that, but it's far more important to growth, future potential, next season prospects, summer plans etc to actually win any cup, finishing above in the league and all that. So I guess if you have the mind set of viewing this season as a process to rebuild properly, then individual freak results don't bother you much and you look at things that actually impact the process or are tangible (finishing top 4, winning trophies, and then how we are progressing in the system and what are the reasons it stalls). If you just look at every season as it's own thing, and don't care about any sort of process or don't believe in that logic of building up a team over a couple years, then yeah you'll care more about every game essentially being it's final form.
For me, I'm all in the process boat, it's gonna take a few seasons to get to City's level, the squads mentality needs to be changed which can only happen over time, and the mentality is a far bigger reason for the big game collapses than anything else (given we outplayed and beat these teams at home). Maybe would be something worth more discussion if we didn't beat them at Old Trafford, but given we did, it's much easier for me to write them off as freak results and a mentality thing more than anything.
