Tactics

Running into space behind a defender when they're focused on the ball or another player. Defenders can't watch everything at once, and the blindside run exploits that. Timing matters - move too early and they'll spot you, too late and the pass is gone. Strikers who are good at this seem to appear in dangerous positions out of nowhere. Agüero made a career of it.

A measure of pressing intensity. Divide the passes you allow by the defensive actions (tackles, interceptions, fouls) you make in the attacking third. Lower number means more aggressive pressing - you're intervening more often. Higher number means you're sitting off and letting them pass. It's a standard stat now for measuring how much a team presses, though it doesn't tell you how well organized that pressing is.

How close together a team stays when defending. A compact shape has small gaps between players and lines, making it hard for opponents to play through. When compactness breaks down - players drift, lines stretch - holes appear. Analytics can measure it by tracking the distance between the deepest defender and highest attacker, or the space between lines. Staying compact requires discipline and fitness.

Passes that move the ball meaningfully towards the opponent's goal - usually defined as 10+ yards forward or any pass into the box. It separates useful possession from sideways passing. Players who rank high in progressive passes are the ones who actually move the ball into dangerous areas. Useful for spotting midfielders who drive play forward even if they don't score or assist much.

German for "counter-pressing." Instead of dropping back after losing the ball, the team immediately swarms the opponent to win it back, ideally within 5-8 seconds while they're still disorganized. Jürgen Klopp made this famous at Borussia Dortmund and Liverpool. The logic: the ball is the best defender. Win it back fast and you catch teams before they can set up.

Deliberately fouling to stop a dangerous attack, usually when you've been caught out on the counter. The foul breaks up play, lets your team get back, and costs nothing except maybe a yellow card. Holding midfielders do it most often. It's cynical but effective, and the punishment rarely fits the crime since the attacking team loses a promising situation for just a free kick in a non-dangerous area.

Loose balls after clearances, headers, or blocked shots. Winning second balls is a skill - you need anticipation, positioning, and aggression. Some teams play direct football specifically to create second ball situations. Commentators obsess over it, especially when one team dominates the aerial duels but can't collect what drops. It's a sign of midfield control.

The moment possession changes hands. Attacking transition means winning the ball and going forward before the opponent can organize. Defensive transition means losing it and either pressing immediately or sprinting back. Both sides are vulnerable during transitions, which is why tactical analysis focuses on them so much. Teams that handle these moments well can control games without dominating possession.

The moment a team wins the ball back and can attack immediately, before the opposition has a chance to reorganise. Fast attacking transitions can cause chaos, catching teams with players out of position who were just on the attack themselves. Some teams build their entire DNA and game tactics around winning the ball back and attacking quickly.

Pushing the defence up towards the halfway line, squeezing the space between defence and midfield but leaving lots of room behind. Usually combined with pressing to pin opponents back and catch attackers offside. You need quick defenders who read the game well and a keeper who can sweep. When it works, it suffocates teams. When it doesn't, balls over the top destroy you. VAR's tight offside calls have made it both more effective and more contentious.
