I understand what you're Getting at, But the days of Xavi-Busi-Iniesta are Long gone. Xavi is 35 and his legs are Gone, to even Remotely Defend or Track back and slows the Game way down. Iniesta Is not the same dude he was During the Peak years. And Busi would Be Left exposed to The Xavi-Iniesta Partnership, from Counter attacking teams and I'm Pretty sure Villarreal is not going to sit back and Park the Bus this Game. The Times we played Xavi-Busi-Iniesta resulted in Failure, against Teams that just Parked it and Vs Real who at the time played Fast counter attacks. Peps Possession System+Old Man Xavi and a Declined Iniesta, will Not work anymore against Teams that Sit in their Own Half.
That's why we have to bring the best out of them through tactical adjustments. To me, our ideal midfied would be Rakitic---Busquets----Xavi --> Rakitic can cover up Xavi.
If we play in our "classic" system that rose Barca to glory, it is indeed true that we will encounter the difficulties that you mentioned... without tactical adjustments. Let me give you an example :
Imagine Iniesta has the ball and we are in our opponent's half :
Enrique's system would look like ( IMO) :
----------Pique----------Mascherano--------
-----------------------------------------------
---------------Busquets----------------------
-Alves----------------------Iniesta(b)---Alba--
-----Messi----Xavi-----------------------------
-----------------------Suarez---Neymar------
Here we would clearly have difficulties with counter-attacks
Here are, I believe, the tactical adjustments we could make, given the exact same situation ( Iniesta with the ball at approx. 35-45 meters from our opponent's goal) in order to bring out the best of this midfield :
----------Piqué----------------------Mascherano----
-----------------------Busquets----------------------
------------Alves-------------------------------------
------Xavi------------------------------Alba---------
-----------------------------------Iniesta(b)----------
--Messi------------------------------------Neymar---
----------------------Suarez-------------------------
Now unfortunately I haven't got any app or software to show you the way the players should/ might move but do you get what I mean?
- This system is less vertical but it allows to stretch widely the opponent's defense --> Messi and Neymar are excellent at breaking down defenses like that when they penetrate our opponent's block from the sides.
- Alves and Alba playing a more central role would increase our dominance and avoid har counter-attacks ( Guardiola does the same at Bayern with a very awkward 3-4-3/ 3-5-2 system).
- Iniesta could alway play a diagonal pass towards Xavi to revive the game in case of saturation ( this would imply that Xavi and Iniesta would have the same tasks to deliver) or Busquets can, of course, assist him in transmitting the ball to Xavi.
But here are the ideas that I wanted to point out :
- Villareal's central midfield would be wiiiiide open if they wanted to go out " all guns blazing" --> if we play with those adjusments they MUST park the bus.
- Villareal would be unable to counter from the centre
- This system, contrary to the previous one, is symetrical and doesn't leave any balance issues ( Enrique has been talking about "BALANCING THE ATTACK").
Of course the hardest part of this system would be to switch on the attacks going from backwards but there is no other better player than Xavi and Iniesta at creating space and building the play.
Don't get me wrong, Enrique is an excellent trainer and tactian, in my opinion, and I do support him. But he seems to have written of Xavi's importance. (Xavi was, to me, our best midfielder from October 2014 and January 2015)
I would have LOVED to show it to you with the movements etc... if any of you knows a specific app/software please share it!
