Second, I think you're perhaps right that Rakitic fits current Barca more than a prime Xavi would. But if Barca had a prime Xavi, the tactics would almost certainly be different. So Barca would be different, and Xavi would fit the system. And, given that prime Xavi is a far superior player to Rakitic (no knock on Rakitic at all; it's just that prime Xavi was godly), I have to assume Barca would be better off for it.
I agree with you here.
But unlike most of our fans, I don't think "too romantically" about Pep's Barca.
More or less, 80-90% of fans here think that Pep's Barca is the best thing that ever existed in football and that our style back then is the best formation/tactics/style ever seen in football's history.
I love Pep and our style back then, but imo, again, that worked because it was a perfect moment in football's history when no one knew how to defend against Tiki-Taka.
Once when Tiki-Taka was figured out, we couldn't win CL trophies even with still almost prime Xavi, Busi, Iniesta and Messi. (Ok, we didn't have Pep anymore, but still..)
Anyway, my point was:
-- Rijkaard's Barca from 2006:
-- a strong Cdm (Edmilson, Motta, Marquez)+ one small/technical Cm (Xavi/Deco) + one extremely physically strong midfielder (Van Bommel/Motta)
-- so, 2 strong guys + weak guy worked back then
-- in 2005, when we lost to Chelsea, we had 3 small midfielders because of a lot of injuries
-- against Chelsea we played with Gerard (Barca's B coach), Xavi and Deco
-- and imo, that was the same old crappy story as always=2-3 small midfielders were more or less EASILY trashed by biggest teams in Europe (and that tactics worked only during Pep, and imo, NEVER before him and will neither work ever again)
So, this is how 3 weaker midfielders played before Pep, but also, the same story was after Pep/after a prime of Tiki-Taka:
-- the same old story imo (I am often posting this video, that was the most painful night for me as a Barca fan ever):
-- 2nd leg, CL 1/8, we won 2:1 in the first match
-- we were on paper the best team in Europe in that moment, when Ronnie-Etoo magic started to rule the world:
-- Pep's era:
-- we survived suddenly with physically weaker midfielders like Busi-Xavi-Iniesta
-- after 3-4 years when Tiki-Taka was on it's prime, short midfielders again weren't good enough for CL trophies
-- and now suddenly, in the first Season when we moved from Xavi-Iniesta, we have again won a CL
-- I don't think that it is a coincidence
I also wanted to say that a lot of our fans from this forum became fans during Pep's era, so they have slightly too romantic views on Pep's era and they still believe that this was the best team ever.
For me, Rijkaard's team from 2006' or Lucho's from 2015' weren't too much behind.
And I don't look at Pep's team as the only way how Barca should play.
In fact again, my opinion, in our last 3 winning eras (2006, 2009-2011, 2015) in 2 times out of 3, Rijkaard and Lucho used more or less exactly the same system (those 2 Barca's are very, very similar).
So, my opinion is, that except in Pep's era during golden Tiki-Taka days, the BEST formation for us is a formation where we combine our insane technique with some muscles from players like Edmilson, Motta, Van Bommel, or Rakitic today.
This is why I think that current Rakitic and his height (183 cms) and some muscles are better in a combination with Iniesta, then any prime Xavi-Iniesta combination.
Xavi-Iniesta worked (imo) ONLY until teams figured out how to defend against Tiki-Taka.
After that, Tiki-Taka became quite predictable, one dimensional and somewhat easy to defend.
