Our weakness is in midfield. The defence is generally OK, other than Walker and Gvardiol who frequently crumble under pressure.
The midfield leave the back three / four exposed far too often.
The midfield creates little or nothing for our forward (singular, not plural).
The midfield makes more sideways moves in one game than Ray Wilkins dud in a full season. They're slow, predictable, and indecisive.
Bernardo, Gundogan, De Bruyne, Kovacic... All done at 'elite' level other than in short bursts. Part-timers.
Foden, Grealish... below par, with no settled position in the team. They both look very average players this season. They're both overrated by fans imo, resulting in too much being expected of them.
Lewis, Savinho, Doku, Nunes... Simply not top level players. Grafters with no end product. They're very lucky to be at a top level club.
We've got two 'full time' world class players. One on crutches for the season, and one running around 'up top' getting little or no service.
Pep can try what he wants. He simply doesn't have the players who can be relied on to deliver the goods over 40+ games a season any more.
Poor succession planning by the club.
