A club's identity, philosophy, and style that's supposed to survive manager and player changes. It covers tactics, values, youth development, and how the club wants to play. Barcelona's possession game, Athletic Bilbao's Basque-only policy, and Ajax's technical youth focus are classic examples. Clubs now talk about DNA constantly when hiring managers. Critics say it can become an excuse for refusing to adapt.

Stands for "Denying an Obvious Goal-Scoring Opportunity." It's the official term referees use when a defender commits a foul that stops a clear chance on goal. If it happens inside the box, it's a penalty. The punishment used to be an automatic red card, but since 2016, if the foul is an honest attempt to play the ball inside the area, it's usually just a yellow. Outside the box? Still a straight red.

Two defensive midfielders sitting in front of the back line. It gives more protection than a single holder and lets full-backs and wingers push up knowing there's cover. Usually one is a destroyer and one is better on the ball. Standard in 4-2-3-1 setups and still common when teams want defensive balance.

The player who lies down behind the defensive wall at a free kick to stop the ball going underneath. As attacking players got better at dipping the ball under jumping walls, teams started putting someone on the ground to block that gap. It looks undignified but it works. You see it at almost every free kick near the box now, especially in the Premier League.

When an attacker comes back toward their own goal to receive the ball. Strikers who drop deep pull defenders out of position and create space for runners. It also helps the team build play by adding an extra body in midfield. Not every striker can do it - you need good link-up play and the intelligence to know when to drop and when to stay high. Firmino and Benzema are masters at it.
