The fantastic Guardiola's Barcelona will not be forgotten, at least to people who knows a little about football. It was spetacular to watch that team not only keeping the ball, but completely dominating the match. It was like they could score at any moment they wished to do so.
To me, that team already had problems. Since then, Barça has been vulnerable against high balls, and counter attacks. But back then, all the players worked better as a team, kept the match under control and everybody was defending much, much better, to the point the opposing team couldn't even cross high balls against Barcelona.
Barça still is one of the strongest teams on the planet, but it is time to change, bring some new players, maybe some more weight on the attack, but especially more people who can recover the ball, cover spaces and fight out high crosses.
