The issues are 100% the left back nonsense we've allowed to get worse and worse for years to the point it's impacted our RB and CB options.
the Keeper has never been a great shot stopper but we've generally been solid enough at the back to make that not an issue, now teams just lump the ball down whatever wing we are doing some experimental fullback bullshit and we concede a chance.
We've had Cancelo, Ake, Laporte, Lewis, Gomez, Foden and Bernardo Silva playing there nominally this season if that doesn't tell you they don't have a clue how to fix it nothing will.
When we play a solid CB out there and try and have the RB pushing into midfield and we get countered down the right rather than left.
We've had our best all round CB (Stones) either playing RB or getting injured being constantly dragged out wide to cover a fullback who's been trying to play holding midfield.
The 2 years of false 9 and extra midfield cover it gave you generally covered for the shiteness at left back as it bunged up the middle of the pitch and reduced the opportunity to counter.
I don't see how it gets resolved before summer, only way I can think is Ake left back Walker RB Stones CB but pushing into midfield when we have the ball
100% spot on.
