Playing Messi in the center has much more value than on the wing because of the linkup with Neymar. Play him next to Neymar and the two will win the match for us by themselves, as they did last night. As far as the midfield goes, that's also Lucho's fault. Remember back when we supposedly had the best midfield in the world? We played a lot quicker then. If you think the reason we don't is the age of our players you should try taking Zubi's old spot as sporting director, as you'd be perfect.
1. Messi and Neymar will alone won matches only against crappy and midtable La Liga teams
-- against any other decent team, we will struggle if we rely (only) on their connection (Messi as a false nine and Ney on LW)
2. our system with with Messi on a false 9 stopped working around 4 Seasons ago. Pep's last Season had some problems. Tito, Tata, Lucho.
-- that system was once awesome. But that was like 7-8 years ago when teams learned how to neutralized our former 433 with Lw-Cf-Rw (Messi on Rw)
-- that 433 system started to be predictable, and Pep moved Messi in the middle to create a new system and new problems for all opponents
=> then it was a new and unpredictable system for some time, and it worked awesome for 2-3 Seasons
-- but then, the same as with a previous Messi on RW system, teams slowly started to learn how to defend against us, and this system, with Messi as a false 9, started to be easy to defend against
-- a lot of people will say that our players are older, they are not on their prime, that we don't run, press, play triangles
-- but imo, you are only as good as your opponent's allow you to be
-- the match is not ONLY about US. It is always about US, but also about our opponents
-- how good we will be, always partly depends on how will our opponents neutralize our system
-- were we awesome yesterday against Elche, or Elche is just a crap and they played with 10 men?
-- the same is with Messi on false 9. It worked in the first Seasons because teams didn't know how to defend against it
-- when Mourinho and some coaches figured out tricks, everyone started to follow him, and we were in huge troubles against any decent team
-- even if we had 28 year old Xavi, 24 year old Iniesta and 22 year old Messi, we would still struggle today with a false 9 Messi.
The age and motivation of our players is NOT the only problem.
Our system was the same and unchanged for 7 Seasons, and other teams have evolved and learned how to neutralize it.
Now, we have finally found "a new trick". And a new trick and some other new tricks will again now work for a 1-2-3 Seasons and then other teams will again learn how to neutralize the current trick.
This is why, even if you are currently winning, you always need to think about some new tactics and some new tricks for a moment when your opponents will learn how to neutralize your current tricks.
It is all about evolving and improving all the time.
This is why Pep was trying new things in his last Season. He KNEW that our current formation won't be that lethal for much long.
Sadly, Tito and Tata didn't know that.
Luckily, it seems that Lucho has now figured out that.
So, a new evolved system is always more important than a 2 men (Messi and Neymar) chemistry or than a single player's statistics.
If Lucho is smart enough, he will continue with Messi on a RW, plus he should be thinking about new "tricks" every day to offer us even more options for the future.
