No it's not coincidence. But it has very little to do with improved midfield, more with the fact that we had one of the best attacks in history of football. You say short midfielders were not enough for CL trophies after few years. You are forgetting the fact that our attack and defense were more to blame than our "weak" midfield. We had just Messi, Villa burned out after one season, Pedro was always average, Sanchez the same (for us) plus some young guys like Cuenca and Tello. So our attack bacame such weakness, that we started to play Cesc as False 9. That's the reason we bought Neymar after all. And our defense after Puyol's play declined with age, became even worse liability.
So IMO the success of this season had more to do with our improved defense (best in La Liga) and Trident, not more physical midfield. Put Xaviniesta in their prime behind Trident and than you could compare.
Ok, let's not go into circles, sorry if I am wrong, but in your reply, all I see is Pep, Pep, Pep's era etc.
So, no mentioning of 90s, early 00s etc.
My experience as a Barca fan:
1994' I watched a final as a kid, and my dad told me: Barcelona is the best team in the world
-- I said: "Ok" and they became my favorite team
-- they lost 4:0 against Milan that night
1995-2004:
-- a bunch of awesome Barcelona's teams where we always had the best or one of the best attacks in the world (Romario, Stoichkov, Ronaldo the Brasilian, Rivaldo, Figo, Kluivert, Sonny Anderson etc)
-- so, attack was never our problem
-- we were always the best in that department
-- our problem was a balance of a midfield and defense
-- we always played either too attacking (Van Gaal) or with a bunch of short midfielders/defenders like Frank De Boer, fullbacks Sergi Barjuan and Albert Ferrer etc
-- 2005:
-- our attack has reached new heights with Ronnie and Etoo
-- but our midfield was still bad with too many small players in Xavi, Iniesta, Deco, Gerard Lopez and with injured stronger players Motta and Edmilson
-- Chelsea again trashed those short midfielders
= after that night, I was pissed and I almost said to myself: I will never again watch Barca's matches, we are just a bunch of idiots with our too attacking football and with totally unbalanced defense and midfield without any height or muscles.
We always play technically beautiful and attacking, but more or less, we always lose in semifinals against any stronger and more balanced team.
I was soooo pissed...
But, luckily, in 2006 Rijkaard figured out Barca's problem and:
-- played with 3 strong defenders in 433 with small Gio VBronckhorst and stronger Puyol, Marquez and Oleguer as a RB instead of shorter (and too attacking minded) Belletti
-- in the middle, we gained some muscles since we played two STRONG midfielders in all matches (Edmilson/Motta/Van Bommel) and 1 shorter midfielder (Deco, Iniesta, injured Xavi)
-- so, who knows, maybe Xavi's injury was the best thing in that moment because we had to play with 2 stronger guys then (usually Edmilson and Van Bommel)
Coincidence or not, we sold Van Bommel and Motta and turned to our golden duo Xavi and Iniesta (plus shorty Deco) after 2006, and of course, we haven't won any trophies after that (yes, we had 1000s of other problems, but still, in the moment when we removed muscles from our team and turned to 100% Barca's DNA, we turned into a good old crappy Barca from 90s)
-- 2009-2011, we won two CLs, but we had Messi on his prime
-- 2015', luckily, we turned to some muscles again and won a CL
I don't mean anything rude, but from watching Barca in the last 20 Seasons, I just personally HATE when we have too many technical players (Xavi-Iniesta) and too few muscles in defense/midfield/and even attack.
My opinion is that we were crap in 90s because we didn't have muscles and because our defense was consisted of short-technically good players.
Our trophies in 2006 and 2015 came from the same formula: Barca's technique+some height, strength and muscles=we become unbeatable machine in those moments.
So, I love Xavi and Iniesta, but I would NEVER again want to see 2 of them or 2 similar players on the field in the same time.
Only Messi can bail similar combinations out.
But imagine a team in the future with 2 small midfielders and NO Messi in the attack.
Imo, that is a recipe for disaster, like Barca in early 00's.
Someone will now reply: what about Spain and Xavi-Iniesta:
= the same answer
-- those were the days when NO ONE knew how to defend against Tiki-Taka
-- and Spain had 7-8 players from Barca who had good chemistry and that was it
= today everyone knows how to stop Tiki Taka and now we need a classic formula for Barca's succes:
1. Barca's technique
2. some height, strength and muscles
3. motivated players
= and that's it
