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.
Arsenal's high defensive line under Arteta requires perfect synchronization. One defender stepping out of line at the wrong moment, and the attacker is onside. The communication between Gabriel, Saliba, and Ramsdale has to be constant.
