I will over the course of next 1-2 months or so do a complete analysis of the Barcelona - Madrid 5-0 game during Guardiola, in 5 parts or so. Will analyze everything, even the parts that don't lead to chances and are as such not included in highlights montages. Even the mistakes, although they are very few.
Hopefully, we will all understand better several important things, some individual things about players like Xavi, Iniesta, Alves, Messi, how they came to be that dominat, things about Puyol even, and Pique at that time, the underrated role of Abidal in the team the consistent and tireless work of Pedro, and even how well David Villa played that year for us under Guardiola. Also it will show how the system was above everything else, and how key players were not passed to just because they were open, and because they were individually better than others. How the mind and governed everything about how we attacked, not just the names on the back of the shirt.
That game and the Wembley final with United, are the best games to watch the full expression of the main principles of possession football. What they are and how are they supposed to work. Which are: position, fluidity, compactness, 3rd man runs, triangulation, pressing and counter-pressing, teammate orientation, overloads in the areas of the ball, ball and man oriented zonal defending with fortified zones and neglected zones. Everything there is to know so we can see what you need to do to play possession football effectively today. And how far are these concepts compared with what you saw under Valverde, and what you will see form this Barcelona this season probably as well.
Also, it doesn't mean I expect all Barca teams to play like that. But it is useful to use it as a model to see what are some of the things we need to do to get close to our best football. And it is not that dependent on players like Xavi. We have City as an example. Fernandinho, Gundogan, Bernardo, Sterling. Neither of these players have anything to do with La Masia or Barcelona, and neither is a generational player. Yet, they can all play like that. It is teachable, and playable even with players like Zinchenko, or low IQ players like Walker, Otamendi. You do not have to understand the complexity of these tactics as a player. You need to listen to the manager, and play it the way the manager asks you to.
