If a post on a City forum is what’s depressing to you, then I envy you.
At risk of seeming like I have to explain myself, my point was that if Akanji was RB, he was staying there. Citing the Munich games for reference when he was a traditional full back and told to simply defend against Coman/Gnabry/Sane.
That 22/23 season was one of the first times Pep went from all out attack to sitting back and inviting pressure if we got ahead in a game. Because we had 4 out and out defenders on at all times between Akanji, Walker (rarely because of the change in tactic), Stones, Dias, Ake. Stones was the only one who’d venture out into midfield but even that was to create an extra body in there to shield the defence and allow those in front to work their magic (as I said originally).
The four CBs was such a thing that Arteta then tried copying it hence seeing Ben White at right back. Or Timber at left back.
Once Cancelo left midway through the season, we went more rigid defensively and it helped us across the line because we were so strong that season.
