I think alot of people here are still confusing terms around "posession football". Its not about having the most posession you can by passing the ball around and not attacking directly and penetrating...like Bayern did today... or like Barca has been doing for a while now.. its about attacking and about pressuring the opposing team like crazy after losing the ball... and the side product of this is more posession. Thats how Barca played at its peak few years ago, not like we play today and certainly not like Bayern plays.
Also, after reading some comments, a reader could get a feeling that Barca played a crap football until Pep came in and that he invented Possession football, Tiki-Taka, beautiful football, actions and everything.
No. Barca played different types of Possession football since always. In 70's, 80's, 90's and in early 2000's.
For example, a match from "the old" 99-00 Season.
Barca lost against Chelsea 3:1 in the first match of QF in Champions league.
We won 5:1 in the return leg:

We played attacking, we played Possession football. We played beautiful, we were dominating, creating tons of chances.
Point is: Barca played possession and attractive football even before Pep and Tiki-Taka. If we move away to some different version of Possession football, the world won't end.
And there ARE other versions of Possession football..
