A growing number of clubs now employ a coach whose entire role is designing and drilling set-piece routines — corners, free kicks, even long throw-ins — treating a phase of the game once left to instinct as its own coaching discipline.
The specialists study opposition marking schemes in detail, building routines around specific mismatches rather than relying on a handful of stock corner deliveries repeated all season.
"A good set-piece coach can be worth several goals a season without a single tactical change to how the team plays open play." — Set-piece coach, professional football club
Skeptics note that a large share of a team's set-piece success still comes down to individual delivery and timing rather than a diagrammed routine — but few clubs at the top level are willing to leave the phase uncoached anymore.
