That result has been coming for Barca this season. They've rode their luck one too many times.
They're simply not as solid and efficient as they were under Pep. I don't know why - whether it's tactical adjustments made by Tito or whether there is a degree of complacency amongst the players - however they don't work as hard in terms of the pressing game and the sharpness of previous years isn't there. It now takes Messi at his best to elevate the team as a whole. It'll be interesting to see what they do in the summer because they clearly need to do something about the output they currently get from Pedro, Villa and Sanchez in particular. Not easy.
Bayern are a brilliant side, however I think the statement made tonight is as much about Barca taking a step down as it is Bayern taking a step up.
Bayern looking favourites to win the whole thing but I maintain some small hope that Dortmund can pinch it somehow.
They've stood still tactically for about 2 years now, and others have caught up with them and in Bayern's case overtaken them.
Even the best sides have to adapt, modify, add new players, implement new approaches. They haven't done that, they're thinking what worked for them 2 years ago will suffice.
