So what? For all their possession, they did their usual trick in the face of organised opponents of pass, pass, pass, pass, and never in a million years looking like scoring until of course, they resort to shithouse antics and the ref buys it and gives them a leg-up. They then take advantage of their own cheating ways, score a goal or two, and then get seranaded post-match despite boring the tits off everyone and needing another favour from the officials to get the result they want.
Football is about diverse talents and diverse tactics, if we all followed this blueprint of Barca's, the game would be boring. All this idealistic bullshit is nothing more than Barca's propaganda brainwashing the footballing public.
They don't entertain, they play a brand of football that suits their player's characteristics. Kind of like every other team in the World actually.
