Tactics

The players who stay back while the team attacks, ready to deal with a counter if possession is lost. Usually includes a centre-back or two and the holding midfielder. Guardiola teams obsess over rest defense positioning - they want numerical superiority or at least equality behind the ball even during attacking phases. Getting it wrong means getting hit on the break.

All the cynical stuff that wins games without playing well - diving, time-wasting, tactical fouls, faking injuries, crowding the ref, winding up opponents. Purists hate it, but it's everywhere and it works. Some players and managers treat it as a legitimate tool. Atlético Madrid under Simeone are experts at it.

A winger who drifts inside constantly, leaving the wide area empty for the full-back to attack. Different from an inverted winger who still occupies wide areas sometimes - the false winger basically plays as an extra midfielder. The full-back provides all the width. Guardiola's used this with players like Grealish, who naturally gravitates toward the ball rather than staying wide.

Passing out from the back through short balls instead of going long. Usually starts with the keeper, centre-backs split wide, a midfielder drops in, and the team circulates until gaps open up. Everyone needs to be comfortable on the ball, including the keeper. Critics say it's risky when you're doing it in your own box. Fans of it say it creates better attacks and more control.
