The Rampart
Clearances, aerials, long balls, height. Five seasons of Premier League data, 1,778 matches. The league is building a wall.

Take-on success has fallen from 51.8% to 37.9% in four seasons. The common is enclosed.

The Stink
Fixed positions, rehearsed timing, collective over individual. The structural return of the dead ball goal.

The Wonder
Forty-two thousand corners. The engineering underneath the set piece revolution, pipe by pipe.
Notes
- When managers trust the kids: U21 substitutions by game state
