Are you implying (prime) Iniesta would have a hard time in 2021?
Are you implying that Pep's football wouldn't be as successful in 2021?
Oh, wait...
Would Pele be as successful today?
Or Maradona?
Or Romario?
They wouldn't.
When you think about Iniesta, you probably think about Pep's Barca = which doesn't exist anymore.
Pep's football can't win a CL anymore.
Spanish football can't win anything anymore.
So, yeah, if you would put Iniesta in a different era and in a different team against different opponents, you surely wouldn't get the magic from 2010'.
About Pedri, imo, you have a clash of two styles at Barca.
Pique, Busi, Pedri are players leaning towards slower, more sterile, possession game, where we have a slow transition and then we pass till death against a parked bus, waiting for a hole in defense or waiting for Messi to pull his magic (or Spanih NT play from Euro 2021).
And then you have Depay, Frenkie, Coutinho and even Dembele who thrive in a faster, more chaotic football with a fast transition and less possession.
And then you get our team where some players want to play faster only to be paired with guys like Busi who is still stuck in 2009.
doesn't matter how brilliant you are on the ball when you're not touching it.
I always have a feeling that he is not moving off the ball well enough.
And when he gets the ball, he plays first-touch-passes too often and passes the ball to someone else (aka leaving a burden of creation to someone else).
Something like = here you go, YOU try to create something.
He would fit well if he would have 2 Xavis around him or in Del Bosque's 460 formation with 6 creators.
But today, in Barca's team without true midfield creators and when the football is faster, I really don't get how will he be a key player in the future.
