I still couldn't fully wrap my head around the new plan from Esperion. But, let's try to make sense of it anyway.
Fukuda is subbing in Takeshima to take that CB spot. So, it's likely that Akutsu is going forward. As for Ashito, at the moment when he shifted inward, I thought he is going to be inverting into a more central role and make plays from there. But to my surprise, he keeps on going vertically from one side to another.
At a glance, it reminds me of Fernando Diniz' Fluminense, just like the video which DesertStorm shared in this thread. Absolutely no structure. Everyone in the team can go anywhere, preferably at a relative point of one another so that there is always an option to pass and combine in a quick pass-and-go manner.
This system allows the likes of Akutsu to join the attack as much as he likes, especially because Takeshima is now on the field to fill in that CB spot.
I don't think the author is planning to make another turn-around where Barca turn the table once more. I think the author is going to end the game in this chaotic Esperion manner. So, I think there won't be a moment where Barca would realize and exploit this system's glaring weakness.
Anyhow, what awaits is of course the long-anticipated combination between Akutsu, Ashito, and Kuribayashi. We will let them cook! 🔥
