Barca had pretty much the same problem against teams like Chelsea in the past but they had an great team with players like Messi, I don't like possession football, it's slow, too intricate and relies on perfect pinpoint passing, Real should be 3-0 up, they just missed 2 very good chances...and this is with little possession.
Chelsea coped with possession football very well, they'll stifle Bayern.
Counter attacking is better to watch and much more effective when used well IMO, it's much easier to destroy teams using this.
