"Positional Play is a style of play where the football pitch is divided into zones and each player is assigned to a zone. Each zone has a different role which means that each player has a different task to execute. If a player moves into another zone, a teammate has to take his place, which is what we call rotations. The goal of Juego de Posición is that the zones and the tasks within them can be occupied and used by different players. Styles of play in football are like languages, and positional play, more than any other style of play, must be spoken in the same way by every player on the pitch."
If this is the new direction, the key will lie in whether we can get all of our players on the same wavelength and speaking the same language all of the time. Presumably Barnes was recruited to fit into this style, having been coached by Company at Burnley, who was coached for years by Guardiola at ManCity, the master of positional play. It's a big ask to make this shift in a single pre-season, but it should be interesting to see how it goes.
