Well all - liderally all - of our conceded goals are from open play and it’s usually a case of more than one error compounded that leads to each goal. Some of the criticism is harsh but then we’re judging by league title challenging standards.
Many of our ‘team defending’ errors start in midfield or higher up the pitch so I’m loathe to always keep nailing Mustafi and his mates for it.
Some tactical errors have been extremely obvious in recent times, eg Kolasinac getting caught way too high and Xhaka or the left-sided midfielder in the diamond not being able to cover him. This seems to happen quite a lot
Mustafi loves to dive in and when it works it looks great but when it doesn’t it usually leads to a strong goalscoring opportunity for them, so that’s why I wish we had someone more rational and intelligent than him at the back
