Damn, i forgot about the Hungarian football team of the 50's, they practically re-invented the sport as we know it: Lightweight gear, pressing in team, triangle associations, modern position 8 (Hidegkuti) and militarizing the league so the national squad plays and practices often.
Rinus Michels claimed his style from them, Cruyff claimed direct influence from Rinus, then Guardiola said the same for Johan although he went over the top with the defensive aspect.
