Long post to follow:
Xavi will have to break relationships with friends to make the reset work. Pique and busquets can't play on this level anymore and they need to be benched / used as subs.
Also, we have to have patience because if the trainings get harder than before, the team will have low performance in games until they reach the required level and trainings return to lower intensity.
I understand his decisions for the lineup and subs, but it's evident they didn't work, it wasn't his fault though.
Miguenza was a let down and we crumbled when alba left, he got better later on, but still he can't play LB.
Dest was bad attacking but also didn't help Araujo with Davies at all, which left our whole right side dead. On top of it, Araujo, who is not technically great, was left with the task to play from the back.
Dembele operates like an amateur on the left, so even though he avoided Davies, he couldn't do much against pavard either.
Then we have depay, who cannot keep possession or pass correctly under any pressing. He has a heavy touch and is slow on reaction. A lower level player.
Busquets couldn't cope with the speed of Bayern players as per usual. Put a cone instead of him and it's the same. And ofcourse Mats dropped another disaster class.
Those are the weakest links for me.
All in all:
GK: need a starter ASAP. Mats is done.
LB: Need a backup for Alba. He is getting old, but is serviceable still. Not first priority to replace.
CB: I don't think the biggest issue is there. Just don't use Pique.
RB: Dani is a temp solution. Need a starter. Dest is a backup at most.
DM: Need a starter. Busi is done.
CM: would keep Pedri and sell fdj in all honesty. We need another starter. I don't think Gavi, Nico, demir are on the required level yet, and don't know if they will ever reach it. Keep them as subs for now.
CF: All are useless. Need starters. Fati could be sub level, injured all the time or a starter. No one knows.
RW
embele is our only threat due to speed but only from the right side. He is serviceable in our current state but only if he doesn't demand a "B'Dor salary".
LW: do we have anyone? Perhaps fati should play here and not cf, I don't know.
Hard times ahead..
