Barcelona at that time was synonymous with invincibility, not to mention ball control, not to mention goals scored and conceded per game, but to get the 6 crowns alone is enough to explain everything.

1. In five seasons, Barcelona won four La Liga titles, two Champions Leagues, two Copa del Rey titles, two Spanish Super Cups, two European Super Cups and two Club World Cups.

2. And in these five seasons in the Champions League matches are into the second quarter finals, looking at the history of the football world can also be called the existence of a historical record, when the Barcelona soldiers without bloodshed, was called by the fans: the universe team, that is the strength of the Barcelona can be imagined.

3. Stability and dominance, when there are not only the top players and mature system, the transmission and control method of play reached its peak, the midfield non-stop to the foot interspersed, looking for loopholes followed by a sudden launch of the attack, as well as the foreground after the loss of the ball immediately after the counter-robbery, do not give the opponent a lot of opportunities to take the ball. Xavi controlled the rhythm, Messi as the explosive point to decide the game.

4. If you blow up in one sentence how strong Barcelona was in that era, there were two teams in that era, one was Barcelona and the other was the other team.
