I won't argue with you, you are clueless as fuck, let's attributes Barca's success to Xavi and Iniesta and Blame Argentina's failure on Messi.
Great logic you have goind there. And now you are saying barca has a top 5 defence in the world

, it suits your agenda this time, i'm sure that not once but several you attacked them when it suited your agenda back then.
You make a poor excuse of a fanboy, willing to trow away everything because someone questions your best player
Mascherano is an excellent player, and used to be the best CDM in the world. He's not as good as a centreback, but much better then most out there.
Pique, altho overrated (people call him the best CB in the world), is still a damn solid player.
Add to that the wingbacks. Sure, pure defensively they are average at best. But their massive pace, and the positionning in barcelona's system allows them to be MUCH more effective then they should normally be.
Thanks to the combination of supreme speed, positionning and teampressure, AND the immense danger of losing a ball to their fullbacks, barcelona managed to create a pretty damn solid defence.
However, as Bayern pointed out. If you can block their central axis and neutralise feed to messi, and grind them to a halt, then suddenly half of those characteristics fall away and then you get a rather average defence on the flank, still pretty good in the center tho.
Barca have a good defense

Its the fuckin' worst. That's tiki taka for you, Conte would kill them if we defended like that.
To me, and here is to a guy who only watches those two in big games in the CL and El Classico, Messi has always looked like the more impressive and dominant player out there.
Messi has looked better in more classico's. Apart from the last 2 years under Mourinho.
Real madrid seriously need to invest in central midfielders. Not ours tho, they can go fuck themselves
