A nice urban myth, yes.
Rakitic is guilty for everything.
And EV is guilty for everything.
Without those two, we will play the best football again and Dembele, Malcom, Arthur, Busi, Semedo, every single player will fix all of their flaws.
Anyway, a video from 2013/14, last round of La Liag, Atletico:Barcelona:
Check at the last 10 or 15 minutes.
We have Iniesta, Xavi, Song (Busi injured), Messi, Neymar, Alexis, Dani Alves on a field.
So, Xavi, Iniesta, Alves, Neymar. That sounds like a good, creative team, right?
Messi should be happy and shouldn't be dropping deep into midfield.
But guess what. EVEN BEFORE Lucho, Ev and Rakitic, Messi was dropping deep whenever he wasn't 100% happy.
And it seems that he started to drop deep since 2013, when a Mister TikiTaka himself started to decline.
So:
2013: Messi dropping deep
2014: Messi dropping deep
2015: Messi dropping deep
2016: Messi dropping deep
2017: Messi dropping deep
2018: Messi dropping deep
2019: Messi dropping deep
Argentina NT team: Messi dropping deep all the time.
So, basically, Messi was happy with a supply only when Xavi was playing.
Now, enjoy and watch the last 10-15 minutes of this match, when Messi was dropping deep even though he had Neymar, Alexis, old Xavi, Iniesta and Dani Alves around himself:
