For me as a general theme, pep has let anxiety get the better of him this season repeatedly and hasn't really responded to evidence as its come in.
His theory post Rodri was play all the passers, at the expense of incisiveness. It's super obvious that when just one of Gundo/Kova/bernardo doesn't play, any of them, the team is instantly improved. More evidence of that last night.
The solution this season to Rodri was to embrace the attack, which his been mostly fit, and try and outscore opponents who may get a goal due to defensive injuries and midfield deficiencies. Instead when it didn't work instead of embracing the attack he's got more paranoid about control and made the issue worse.
What pep has tried to do has failed, if he plays all the passers the side effect of no pace/physicality undoes any control gains he hoped for and does nothing to resolve defensive problems. What it does do though is completely stifle the attack. Watching Gundogan try and crash the box is a tragic sight at this point in time and I think our absolute worst moments this season have him in the 10.
Pep is the greatest, but his sort of inability to react to all the passers equals fragility and lack of pace and attacking problems outcomes, well it feels like the first time Ive seen him be stumped by a problem and not eventually get to the right solution.
I think he's earned the right to get it wrong for a year, but I do think he's gotten it wrong this year
