Barca's history in short in the last 20-25 years (since I am following Barca) was more or less:
90s (except 1992)=in general we always played too attacking, too naive, didn't have a good defense or we did have physically too weak players
early 00s=the same story. Either too attacking, too naive, physically weak players or poor defense (or more or less, we were poor in all of those things)
2005 and 2006, suddenly Rijkaard turned our naive and physically weak team into a Barca with flair, but also with more muscles (strong defenders Puyol/Oleguer/Marquez, strong-walls Cdms Edmilson/Motta/Marquez and somewhat stronger attackers like Ronaldinho, Etoo, Larsson)
2009 and later, Pep's obsession with extremely short players who can keep the ball till death.
But, but, but...
People always reply in similar debates how we had our best years in our history when we played with SHORT midfielders.
But, there is one huge BUT here (imo):
We had our best days NOT when we had short midfielders, BUT when we had ONCE IN A LIFETIME PRIME XAVI-INIESTA-MESSI.
I would dare to say that our system alone regarding short players who will keep the ball=is NOT that good as people think.
More or less, we played like that in 90s and 00s and we were NEVER good enough to win CL trophies, except in 1992 (but that even wasn't a CL like current's CL), and in 2006 when we weren't playing with weak midfield but with a mixture of muscles and technique (RB Oleguer, Cbs Puyol and Marquez, Cdm Edmilson/Motta, Cms Deco and Van Bommel). Look how much muscles we had back then. And we managed to win against Chelsea (who had insanely physically strong team and Milan, the same). Something which current Barca can't do and we are losing over and over to physically strong teams (the same as in 90s and early 00s).
So, more or less, our biggest problem in Europe was never Real Madrid, Man Utd, Arsenal, Porto and other teams who play attacking football.
Our problem were always Juventus, Milan, Chelsea, Bayern and Atletico. Physically strong teams who neutralize our physically weak midfield.
So, if we are planning to go back to midget midfielders, we really have to ask a question: has that shit ever worked in Europe except when we had Xavi and Iniesta?
Further, about your reply how Real is winning with Modric and Kroos, well, you don't see a larger picture:
1. Barca's midfield: midget players
2. Barca's attack: midget players
What is our only option=to play shortpasses and dribbles till death.
When the opponent like Juve or ATletico stops us, we can't have a plan B since all our players are midgets and there isn't even a chance to have a plan B.
Real?
Casemiro-Kroos are for the start stronger than Busi-Raki-Iniesta.
And on top of that, their attack is way physically stronger and not one dimensional.
CR7 can score with feet and head.
Neymar can't score either with feet or with head.
Benzema can score with feet and head.
Suarez can score with feet and from time to time with head.
Bale can score with feet and head.
Messi can score only with feet.
Do you see a difference?
Real has both a physically stronger midfield than us.
Plus, they can play a plan B with crosses since they have at least 3 tall/strong players in the box (plus Ramos).
Now let's go back to Silva-Raki-Busi-MSN lineup.
Imagine a match against Juve or AM.
Imo, it will end exactly the same as always.
Remember:
a midfield with short players never worked:
EXCEPT:
In 2009 when we had prime Xavi-Iniesta-Messi.
Barca after Xavi sucks.
Spain after Xavi sucks.
Pep after Messi+Xavi+Iniesta sucks.
Once again, Xavi was the brain of Tiki-Taka football.
That kind of football or any later versions of it worked ONLY when a team had Xavi.
Barca is more or less a crap in that type of football without Xavi.
Spain is a crap past Xavi.
Pep and his possession based teams are a crap without Xavi.
So, people should ask themselves, is a Barca with physically weak players a way to go?
And is trying to copying Pep's era, but without prime Xavi-Iniesta-Messi, really a way go?
For me, Rijkaard's football is the way to go currently.
A mixture of Barca's technique and some muscles in order so that we can respond to teams like Atletico, Juve and Bayern.
Try to compare Rijkaard's team from 2006:
Cdm Edmilson 186 cm (and not weak like Busquets)
Cm Deco 174 cm
Cm Van Bommel 187 cm (not weak like Gomes)
Lw Ronaldinho 181 cm (way stronger than Neymar. He wasn't falling on the ground in almost every duel)
Cf Etoo 180
Rw Messi/Guily
And a sub for all Lw, Cf, Rw positions: Larsson 175 cm (who wasn't tall, but he was banging headers like crazy, as a plan B)
Compare that too:
Bernardo 173 cm, phyiscally weak
Rakitic 184, slow and tired
Busi 189, tall but physically weak in duels
Neymar 175, weak physically
Messi 170 cm
In Rijkaard's days, we could score headers by Ronaldinho, Etoo and Larsson.
Since Pep, we are a one dimensional team for 7-8 years already and we are stuck in that era.
Today, our only sub for MSN is poor Paco.
Back then, our subs for Ronnie-Etoo-Guily were Messi (lol) and Larsson.
Imagine having someone like Larsson even today for scoring goals either with feet or with head
(But then, we have MSN and we can't have subs, that is a huge burden. Plus, MSN are built around individual plays, dribbles and playing on the ground.
So, we are stuck either way.)
Anyway:
