I don't want to deny the Messi influence on the recent success but your assumed numbers are exaggerating. Messi didn't start this golden era. It was already started when Ronaldinho and Laporta arrived. Messi just got there at the precise moment and led it to an even more glorious era. Whether it was coincidental or not the golden generation coming out of La Masia synchronized with it also helped Messi to be at the right place and the right time, so it's more than just having "Messi alone". By your logic Argentina should also be sweeping titles left and right now because they have Messi too, but they are not. So your argument of "Messi is 80% or more of our success in the last 10 years" is pure oversimplification of yours and definitely not the whole truth.
The bigger reason why the club has reached this momentum IMO is the stability they have tried to build within their system after so many years of hasty and mindless spending. They got many of their crucial signings right, they have found the right manager to work along with their own plan and continue to work on those specific goals. They recognized and developed the right talents within La Masia. It's a very collective effort that got us where we are now. Your argument of "Messi is 80% or MORE of our success" is quite disrespectful for all the efforts many people has done over the years inside the club to help the club reach where they are now.
Yeah I've been there before and I've seen the mess in the past. It wasn't as "painful" as you say tho. More like anger from watching the chaos inside the house. Watching all these new faces that come and go with insane amounts (at that time!) without a clear plan as why they are here and then they are not anymore. Without the collective effort the club has done over the years even this Messi couldn't deliver as good as he's done in the past years.
We had only one successful season with Ronnie and Etoo (in CL terms).
So, it wasn't a start of an era, but more like a random season when one out of top 4-5 teams win a CL.
The same as sometimes Man. Utd, Bayern, Chelsea, Juve or any (top) team eventually wins a CL once in 10-20 years.
Comparison Barca vs Argentina, well.
Barca (without Messi) was always one out of 4-5 top teams who are equal.
-- in numbers, let's say it this way:
-- strength of Barca without Messi=99%
-- strength of Real without Messi=99%
-- strength of Bayern without Messi=99%
-- strength of Chelsea without Messi=90%
= Barca with Messi=150%
Now, in normal terms, each of these teams have equal chances.
So, sometimes Barca will win a CL, sometimes Real, sometimes Bayern, sometimes a team live Liverpool, Arsenal, Man. Utd, Porto etc.
But when you get a player like Messi on a lottery and when you add him to a team which is already EQUALLY as strong as any top 4-5 team in the world, well, then you get Barca from the last 10 years with trebles, sixtuples, 120 goals scored per Season, pure magic on the field, and 3-4-5 CL titles in 10 years.
Without Messi, I am repeating, we will just be a random top team who will be 50:50 against any random top opponent.
We won't be favorites against any bigger team.
Now, Argentina.
The difference between Barca without Messi and Argentina without Messi is that Argentina without Messi is not in top 4-5 teams in the world.
And Argentina WITHOUT Messi is surely not as equally as strong as Spain, Italy, Brasil or other top teams from the last decade.
So, you see, when you add Messi to already world class Barca=you get a team out of this world.
When you add Messi to pretty average Argentina's team=you get a world class team.
But in numbers:
-- Spain 99%
-- Germany 99%
-- Italy 95%
-- Brasil 90%
-- Argentina without Messi 70-80%
-- so, you see, when you add Messi to that team, Argentina is WITH Messi equally as strong as other top teams, or honestly, STILL WEAKER than other teams.
So, someone could reply now: so, you see that one player alone can't do wonders (Messi in Argentina).
True, to some extent.
But Messi, on a club level, is the only player in a recent football's history, who was able to turn an already world class club (per-Messi Barca) into a team out of this world.
My point is, there isn't OTHER single player in the world whom we can buy and for whom we could say: now with this guy, we will be 2 levels stronger than any opponent (I am talking about era before Messi or after Messi).
So, when Messi will be gone, we won't be able to say: buy Neymar or Hazard and you will be the best team in a world by far.
Lol, that won't happen ever again.
Some players will strengthen our team, but none player ever will strengthen our team as much as Messi did.
Again, I am willing to bet with anyone what will happen in 3-4-5 years when Messi will be gone.
Imo, people are giving too much credit to La Masia, our board etc.
About La Masia, I replied already, if we didn't have Messi, who knows if Xavi, Iniesta, Puyol and other guys would won any other CL than a 2006's title.
You will say that Messi was lucky to play with golden-La Masia generation. True, to some extent, everything clicked perfectly.
But also, if we hadn't Messi, then nobody would hail our golden La Masia's generation.
They would have 1 CL title, 2-3 La Liga titles, and zero trebles, sextuples etc.
Without the collective effort the club has done over the years even this Messi couldn't deliver as good as he's done in the past years.
Ok, but.
If today we have:
= Messi+good work by the board+golden La Masia's generation=current team
But, imo, if you remove some of the factors from the maths, like:
= good board+La Masia but WITHOUT Messi=we would be a crap
= Messi+good board but WITHOUT La Masia=we wouldn't be as good as today, but we would still won 2-3 CL titles in 10 years
= Messi+La Masia WITHOUT a good board=we wouldn't be as good as today, but we would again won at least 2-3 CL titles in 10 years on the wings from a pure quality from Messi and La Masia players
So, yes, you need all factors to create a team like the current Barca.
But still, imo, by far the most important factor was Messi.
Anyway, for those who don't believe, in 4 years, we will still have a good board, and good La Masia, Neymar and other guys, but you will see that it won't matter too much when Messi will be gone.
So, basically Xavi-Iniesta, Deco-Dinho, Puyi-Marquez-Pique-Abi, Henry-Eto'o were shit and would have been playing with 2nd or 3rd tier clubs around Europe.
All hail messi who got spain back to back Euros and their first WC too. It's just because of Messi yo!
Answered above.
Barca without Messi was already EQUALLY as strong as any other top team.
So, Messi was just an insane bonus which turned our team into a bunch of (unbeatable) aliens.
Argentina is a joke out of a team without Messi.
But again, wait 4 years, and you will see how the world (Barca's world) will look without Messi.
You will have all new Puyols, Xavis and similar new La Masia's boys, plus Neymars, Pogbas and other boys.
You'll see how it will work then...
