I didn't read it.
But my remarks are about guys who often quote Cruijff and his words: "technique is more important than physique" and then these guys take it literally for the year 2018'.
20 or 30 years ago:
1. each midfielder and attacker had way more space to run and do tricks before the opponents tried to tackle him
2. each midfielder and attacker had way more time to think what he will do until someone will try to mark or tackle him
3. all your opponents were slower, shorter, with less muscles and stamina than today
So, this is not about Xavi, but for 99% of other players. Things which worked in 1988, 1998 or 2008, don't work anymore (or are less lethal) than in 2018'.
For example, a short video of Real vs Barca in Cruijff's early years as a coach in 1988/89:
Look at strength, muscles and stamina of players back then.
Look at how crappy they are at pressuring the opponents.
Look how horrible are both teams in defending.
Look how much space are teams leaving everywhere on the pitch: on wings, through the middle, around the box.
Look how much time players have until someone actually tries to tackle them.
This video looks like a totally different sport than today's football.
Or, this video looks like a segunda division match from semi amateur teams in 2018'.
Of course that Cruijff's ideas about technique worked back then because you had 3-4 seconds to decide what you will do and you had a free space everywhere.
So, smart and technical players were in a huuuge advantage back then.
This is why I "don't like" posts: Cruijff said this or that about technique and we always used to play with short players.
In 10 years, new kids on internet will laugh at 2009's final and they will ask: wow, why were players slow like grannies back then? This is so strange to watch...
And I am not saying that Paulinho/Gomes is the way to go.
But if 20 years ago we had players with:
Technique 10/10
Physique 2-3/10
And if our opponents today have:
Technique 8/10
Physique 8/10
Then we'll have to raise our bar also to something like:
Technique 10/10
Physique 6/10
