Running inside a teammate who has the ball wide, usually into the gap between full-back and centre-back. The opposite of an overlap - you go inside rather than around the outside. It pulls defenders, opens passing angles into the box, and can create shooting chances. Works well with inverted wingers because when they cut inside, they create space for the underlap.
Kyle Walker's underlapping runs at Manchester City perfectly complement the inverted positioning of his wingers - as the winger drifts inside, Walker surges into the channel between full-back and centre-back, arriving in the box unmarked.
