A Positive Change: The Defence

Yes, there are plenty of reasons for frustration with our attack but something tells me this can be sorted eventually, and we even saw some signs of it returning today with players like Bernardo coming back to life, Gundo given more creative freedom to be more effective and the chance creation much better than I can recall most of this season because Pep chose to push forward more.
If/when we get Sergio back and/or sign a lethal finisher this summer by next season, or maybe sooner, the dedication to solidifying the defence may pay off because of how it has hurt us so badly even under Pellegrini.
Pair Pep’s attack and a few different faces with the way our defence is playing and we might score a few less, but we will also concede fewer.
We not only have 3-4 top class centre halves who are barely, or not even in their prime years yet, but Walker who has been consistently fantastic, and Cancelo’s settling in as a decent LB option. I know he can be poor at times, but he also has moments of good defending (had one today and is such a threat going forward. We will need another LB as Cancelo also will be there to replace Walker as he ages out, but these are all good things.
I was thinking we are done in CL and PL after the West Brom match, but I have begun to think more that Pep is adapting, realising he needs to make us more sold in defence, even if there are some sacrifices in the short term to performance, because this is what has hurt us time and time again (other than finishing, yes I am aware).
Going with the double pivot so frequently is a way of practising more solidity, so the side is more used to it when needed in a big fixture away, for example.
Today we didn’t go with the double pivot, but we still didn’t concede against a high powered attacking side in good form who was at home. I wonder if this isn’t as much a coincidence as part of being trained in taking more care.
I know some are angry about us trying to walk it in instead of shoot, and I’m not saying that’s not frustrating, but I was wondering aloud if this is also an instruction to prevent counter attacks from long, low percentage shots that leave us vulnerable on the break when we don’t have a Fernandinho to help. You work with what you have.
Maybe some of us pushed the panic button too quickly, me included. There’s A LOT more to do, and there are concerns but the times we won the league it was with a strong defence.
Fans love Mancini for the resolute defence we had with Zaba/Micah, Komps, Lescott and the more attack minded left backs Clichy/Kolarov.
Pep trying to bring that back and the transition from brazen attacking to this might involve some growing pains, but perhaps it may pay off for us over his last 2 seasons.
