The touchline is the best defender. Pep Guardiola
Van Gaal’s teams press in a fluid shape, compacting central areas and forcing opponents wide, where the touchline is used to restrict space for opponents before intensifying the pressure.
The problem begins by passing the ball to the fullbacks. You only have quarter of the pitch left. That’s all the full-back has and once the opponent starts putting pressure, he has no option but to play it back to the goalie. Johan Cruyff
Another of Pep’s influences talking about the use of the touchline as a defender.
