Players will adjust to accommodate Wingbacks making attacking runs. They will shift or drop to cover their space while the Wingbacks are out of position.
If one Wingback has pushed up to an attacking position, the rest of the defensive line will shift to cover and play in the shape of a 3-back
If both Wingbacks push up to attacking positions and a Defensive Midfielder is on Drop Between Defenders then the two Center Backs will increase their width to allow the DM to drop between them and play as a 3-back
