Paris St-Germain, the Champions League holders, are currently leading their team into the semi-finals of this season's competition and are considered strong contenders to repeat their impressive performance. Despite having a number of top players such as Lionel Messi, Neymar, and Kylian Mbappe, Luis Enrique's team has been playing the club's best football this season. The team's tactical fluidity and rotations have allowed them to perform well against top teams in the world, with players moving into different positions to provide balance. The concept of 'floaters and anchors' has been used to explain this concept, which involves players who act as anchors occupying zones that provide balance, such as the two centre-backs, touchline players on both sides, and one player stretching the opposition up top. The rotations can be described as 'zone replacements', which are often spontaneous but precise and predictable. Despite this, PSG's players are given more freedom to move around the pitch. They replace each other's zones without dropping off in quality, which is dependent on player quality.
