Tactics

The imaginary line connecting the back defenders, which determines the offside position for attackers. A flat line is easier to hold but harder to adjust; a staggered line offers cover but can create gaps. The defensive line moves up and down as a unit - holding the line is essential for the offside trap. Calling the line, stepping up, and dropping together requires constant communication.

Short passing, constant movement, keeping the ball. Barcelona under Pep Guardiola (2008-2012) and the Spanish national team made this style famous. The idea is to hold possession through quick triangles, pull opponents out of shape, and find gaps through patient build-up. Every player needs good technique and the discipline to stick to the pattern.

Creating numerical superiority on the flanks. The winger, full-back, and maybe a midfielder all move to one side, outnumbering the opposition's full-back. It creates crossing opportunities and drags the defense out of shape. The risk is leaving the other side empty if the overload doesn't produce anything. Teams balance wide overloads by having players ready to switch play quickly.

The Dutch system from Ajax and the Netherlands national team in the 1970s, developed under Rinus Michels and Johan Cruyff. The core idea: any outfield player can swap into any other position. A defender becomes a midfielder, a midfielder becomes a winger, and so on. It demanded versatile players who could press together, spring the offside trap, and switch between attack and defense quickly. Still talked about as one of the sport's great tactical experiments.

Same as a third man run but emphasizing the passing combination. Player A passes to B, who lays off to C, who passes to A running beyond - it's a quick combination that uses the third man to unlock space. The timing and execution have to be sharp. When it works, it cuts through defenses that are set up to deal with direct passes.
