This is an excellent summary of the FC Barcelona approach to football.
Don't just watch the Barca player with the ball, watch the ones off the ball and how they move. Charlie Cooke (Chelsea FC Legend and Coerver co founder) refers to these passing movements as "Sequences of play", involving 3-4 players, different players in different parts of the field, but all replicating these sequences of play, no matter where they are on the field of play. And that's the big difference between Barca and others, their ability to construct these unending sequences of play, which in turn most often see a significant possession count in their favor and of course, goals. And when they loose the ball, look at how quickly they usually regain the ball and it starts all over again. Wonderful.
Take the time and have a look.
Then start doing some of this at your Club.
