Overloading

When more players than usual penetrate a zone, then we can call it overloading. Especially flanks are often zones where teams can overload with central players who move to the outside, as the opponent is forced to react or the attacking team can outnumber the defenders. Either they let the central midfielder drift wide, and his presence with both the winger and the full-back makes it three-on-two out wide or they follow him, but leave space in the centre of the pitch for wingers or onrushing midfielders to take.
