The world has uncovered our weaknesses and the way to take us down.. there must be a change in the way of play now. the fresh new style era is over, theyve found us out.. 

We need to put more emphasis on defence, by buying taller and stronger defender's (Puyol alone is not enough,Pique has lost his mind, for some reaSON villanova and roara dont want to use song, and alves is fast but too small. we need to fight fire with fire, treat teams the same way they treat us. but at the same time have enough attacking firepower to combine it.

congratulations to the old enemy.you kicked our asses like weve been kicking your asses for the past 4 years.

i agree

and how is that the system worked well for 4-5 years and suddenly, everyone seems to have figured it out?

Give them a break. Bad form at the moment and the fact Tito isn't there to guide them is costing Barcelona. Seems like everytine Barca lose a couple games everyone goes nuts. Tiki taka still works and it will remain to work. When Barca is inform and accurate and finish their chances they win every time. 

@Fred teams have realized many times but they are in different leagues...

Inter
AC Milan
Chelsea

etc.

If Manchester Utd parked the bus on us, we would have lost the CL

@ramaboy

Not necessarily. So many teams park the bus against Barcelona, but only the very talented and clinical come out with a win. Madrid has had the best record against them in the last few games, but they face Barca regularly. We've learned to be clinical. But the other teams have to make sure that they make the most of every counter-attack, because it's not often that Barcelona give up possession. And like raimondo said, relax guys. They just messed up a few times, largely because their trusted leader Tito Vilanova is not present at the time. Also they need to give Messi a break. No matter what he says, he is still human and he still very much can get tired, mentally and physically. Playing 50+ games per season isn't the brightest of ideas, even for Lionel Messi. Just give him a 2-3 game break with only sub appearances in the 70+ minutes and he'll be back to his best.

I think you guys are overreacting. We are just too used to winning but we have to learn how to accept a loss, we will be back up soon. Our manager is not there and the players are tired. Our style has been figured out years ago but it's so complicated that only the most disciplined, the most fit and smartest of teams can properly defend against it. But the thing is not to change it, but to have a backup. To learn how to reel players from their own half into ours and counter at the right moment, etc. I think we need a new center back, and most especially a new winger who can FINISH!! (hint hint play VILLA).

Oh sorry guys I basically posted the same thing as Dynastian.

No-one wins everything, all the time. Not even the best team of all time (which they are).

Even if teams are now able to challenge Barcelona more often, and they're not so head-and-shoulders above everyone else, expect this team to still be the one that no-one wants to be drawn against.
