I'm starting to think Barca are having a bit of an identity crisis.
Seems daft despite the excellent start, but bare with me. You don't seem anywhere near as considered in possession as you were under Guardiola. There seems to be far more forcing the ball forward quickly, and also a lot more crosses from wide positions, trying to overlap the fullbacks and stretch the play. I even saw a lot of long balls straight from the goalkeeper/defence. It's as if Vilanova is trying to mix things up with direct play a lot more in response to games like the Chelsea one last year where you ran out of ideas - but I don't think it's working all that well and is sacrificing the measured domination that you normally have.
Maybe I'm just being daft, but I'm yet to be completely impressed by Barca this season and you seem sloppier with the ball than usual. Worrying considering the current CB partnership.
