I didn't use it but I remember it, quite successful indeed.
This is the concept I like most, to control the match and by control I mean that it's both defensive and attacking. For my experience, it's more about knowing how to match player roles and right TI (team instructions) than mentality and this because I've used almost all: Attacking, Control, Standard and Counter and all of these have concepts that make us remember the good old Pep's Barcelona (or the current Bayern with several differences because of the different players): attacking - means possession is used mostly by the defensive players and accelerates at front (check); control - tries to build patiently looking for spaces (check); standard - it's both defensive and offensive (check... since tiki-taka was neither offensive or defensive, it was both - one of the key concepts); counter - because it allows to move the ball around deeper without crowding the space near the opposition goal (check). Quite impossible to make a mix of all these in one mentality
. On the top of all this, we have Guardiola him self stating that it likes speed, high speed (does high intensity translates faithfully ???) and Fabregas stating "every player has a specific duty" (this would mean Balanced team shape in FM terms) and "we have freedom of movement with the ball, not without the ball" (not sure how this translates). Finally, there might be something to work with the so called "runners" and "passers": those players roles which have automatically activated dribble frequently and those who don't, so I'm just wondering that wingers might not fit into the concept.
Would like to read your thoughts on this
and congratulations for your work.
