The criticism is going over the top and BTW as great as Pep is, for me perhaps the best ever, for periods he can also help to create this sort of situations in the way he manages his teams. BTW not a single forward or off mid in this last game played great.
At some point with the heavy rotation, with the team and mostly system above the individual, sooner or later players began to loose confidence, in other situations the system applied does not suit the best traits of some players and so on.
Discussing Pep's methods is lunacy, because the results are there to be seen, but in general he ain't precisly a fella that thrives to put players above his ideas and there are moments, games, periods that this can create a new great role for some, or in the other spectrum dimminish the level of others.
Erling right now, it's not a great player to be surrounded by many, to feel pushed agaisnt the rival's final wall and his mates behind him operating in tight spaces at the pace of a snail.
He still will have that killer instict for second balls, for being in the right spot, but as soon as he gets game after game more uncomfortable, he'll loose his sharpness.
Also by this time regarding Erling, teams know better how he operates.
Of course the Viking should do better in more than one ocasion (it's silly to defend some of his plain and simply mistakes like not hitting the fecking the ball), but also should in prior games Alvarez, Foden, Kevin and such. Their system is so good to mantein their form, that even with many players not precisly in their best form, they still can compete, be compact, win or to teh very least not loose, yet at the same time they are loosing the spark. City sometimes plays so safe that players as diff as Alvarez and Erling, but that both thrive on running to channels and open space does this just receiving a single or couple of balls throw entire matches, so at some point, with all the changes of roles, positions, of the for moments excessive holding of the ball, it begans to play against the best tratis of some of his players and these felals start to loose their sharpness.
This by no means, means that the players should do a lot more, but it's quite more of a mixed bag the whole situation than pointing merely to individuals.
PD: All in all, the excessive praise on Erlin's unique traits from older posts and such, was extremely pushing over the overal talent of the man, yet going to the opposite extreme, it's sillier.
