Some people say it can't be done.
This is actually quite correct.
It can be done, meaning that if a player is excellent enough, they can indeed possess both strong offensive and defensive abilities, as is the case with Lu Yang rampaging in the Italian Third Division, speaking from a capability standpoint.
It can't be done, is from a spatial and temporal standpoint.
On the field, if you want to attack, you inevitably need to reach the attacking third, and when a defender goes there, their defensive third is left unmanned.
The so-called three zones refer to dividing the football field into front, middle, and back parts, with the area near the opponent's goal being the attacking third, the midfield being the second attacking zone, and one's own half being the first attacking zone.
And defense is the opposite, with one's own side being the defensive third and the opponent's side being the defensive first zone.
No matter how strong your abilities are, you are still only one person.
