When we didn't have Coutinho and Dembele, Messi was dropping deep to get the ball and he was involved in a build up of probably 9 out of 10 of our actions.
Iniesta played on a left.
So, when we had only Iniesta and Messi on a field, it seems that we suffer from Messipendencia, but on the other hand, Messi is involved in EVERYTHING all the time.
And whenever Messi is involved a lot, usually awesome things happen over 90 minutes.
When we had Neymar, Iniesta and Messi, we had a similar problem.
3 creators and Messi wasn't involved AS MUCH as when only Messi and Iniesta are on a field.
Neymar was "taking" a huge part part of Messi's actions and that meant=less balls for Messi.
Less balls for Messi usually ends in less chances for a team than=more balls for Messi.
Now, when Dembele started to play, we have already seen a problem that he occupies a similar area to Messi's area.
That means:
1. either less balls and less room for Messi (which is NEVER a good idea)
2. or Messi will keep his area (dropping deep and being involved in buildup all the time) and less balls for Dembele who is then useless on the RW
Now, Dembele is injured.
In the first Coutinho's match, he played as a LM-LW and everything worked well with Coutinho and Messi on a field.
Their areas weren't clashing.
Coutinho was creating chances and Messi was still able to drop deep to be involved in a build up in his central area.
But now, with Iniesta on the left, Messi in the middle and Coutinho on the right, it was just too crowded.
Messi wasn't dropping deep because Iniesta and Coutinho were behind him.
So, Messi was less involved in build up (which is not good) and he was somewhat lost and confused around the box.
To some extent, he seemed as if we turned him off the game.
When Coutinho left the field, Iniesta was the only guy in midfield who is creating and since Coutinho was not occupying Messi's area anymore, Messi was back to his normal self with dropping deep and being involved a lot in every action.
And we played better.
So, EV will need to find a formation which will keep a formational balance, plus a lineup in which players won't clash with their teammates.
On the other hand, imagine the worst possible lineup:
Luis, Messi
Iniesta, Coutinho, Dembele
Busquets
Messi couldn't drop deep.
Iniesta and Coutinho would clash among themselves all the time.
Plus, Coutinho and Messi would clash with Dembele (and Roberto).
A total mess.
Some posters mentioned that we could play 433 with Iniesta-Rakitic-Busquets and Coutinho-Luis-Messi in attack.
Ok, fine, that could work better.
But then: where will a 150M Dembele play?
I currently can't see a lineup where Messi, Luis, Coutinho, Iniesta and Dembele could coexist.
In fact, I can't find a lineup even for Messi, Luis, Coutinho and Dembele.
