I'd argue the philosophy was Structured. For Guardiola's tactics circa 2011ish you're going to be playing a 4-3-3 that's narrow high up the pitch with width provided by full-backs. More to the point, you're going to have at least three specialist roles: Messi as a false nine, Iniesta as an AP support and Xavi as a DLP support. Add to that theoretically Busquets as a modified Regista and you've got four, and with Flexible things will just get too disorganised. Also I guess I'm a Structured philosophy *****.
Fully agree on the structured part. There was an awful lot of movement but that movement was also to always maintain the shape of the formation. Wasn't Busquets more a half back though with the way he dropped back into the defensive line?
PS. Structured philosophy ***** here as well
