We'll have to disagree to agree.
First off you don't readjust and expect a team mate to cover behind you, especially as the danger has yet to be dealt with.
And secondly, you don't rest your shoulders and take a stutter step when trying to defend a first time ball into the box at the near post.
It ended at the back post but it should have been dealt with near post.
@Eugenius put it perfectly. Lindelof does everything right zonally (position wise) but he failed to deal with it proactively. Same with AWB.
Almost exact same scenario as against Sevilla last year. Both in 'good' positions but both just switched off at the last second.
