It is strange to read so much negativity on this forum, since it is such a joy to support a team of this quality and entertainment value. For all of you crybabies, please explain how the world's worst defense has given up only one goal in the first 3 games?
I don't consider this to be a rebuilding team. Last year, this was the #2 team in the world, per the results. Bayern peaked at the right time, and Messi got hurt. In the first half of last season, Barca was best in the world. Going into this year, of course there are signifigant uncertainties with a new coach and blending in a unique talent like Neymar. But Barca lost no key players, and added the South American player of the year, the MVP of the Confed cup. With just a couple of exceptions, the team is plenty young enough. Cesc and S. Roberto are fine depth if Xavi is fading, though this fading Xavi is still pretty damn good.
For depth, the only concern is CB. The team has superb talent all the way through the first 20 or so, which is as many good players as you want since only that many will play much at all. Some CB will be added this last week, we'll see about his quality. For these crazy clubs who a now adding their eighth offensive midfielder, fourth single striker and so on, we will see how their 30 man squads hang together over the long season with all that big talent not playing at all.
