I hope Tito recovers from his health issues but really think it would be the best for all parties if he resigns after this season.
If he stays another season the era of this great team really could be over.
I'd like to repeat what a lot of people here said, barca played alot better last season although there where early sings of decline which a attribute to lack of drive due to complacency.
To those who said the false nine is dead, it worked because other players exploited the space created by messi dropping deep, which is not happening this season, the wide players moved inside, which is not happening this season.
Pressing is a lot worse this season, the defence which may not include players with classical defensive attributes (eg,Mascherano ) worked because of the relentless pressing and the high line, most of the time penalty box defending was not needed because the ball was already won back in midfield.
Under Vilanova, the "hunting in packs" style of pressing is non existent,players press individually and the whole team plays deeper which allows teams to directly expose the defence which is a reason why they are looking so weak this year.
I truly hope the board does react, even though it is a difficult situation, firing a man who is fighting for his life, but something has to change.
As for new managers, maybe Villas-Boas would be an option, he would play a similar style while still bringing in fresh ideas.
