What is an advanced area in football (soccer) field?

Question

In this article Tactical Theory: Vertical Build-Up Passing the author used the words advanced area for many times, for example

Every team utilises different build-up patterns in order to move into more advanced areas of the pitch

or

But midfielders, who have more license to move into advanced areas, can combine passing accuracy & aim with runs of their own.

Could you please explain for me what is an advanced area? I wonder is there an official definition of advanced area or it is just the dangerous area in opponent's field?

Answer 1

To advance is to move forward; to be advanced is to have moved, or be in a position which is comparatively, forward of some other place.

In football the primary division of the field is the half, by the centreline. Thus, an advanced area is best understood to be one which is forward of the team's own half, i.e. a position in which that team is attacking.
