So, just to make it clear, you admit your dislike for young players?
Young players do not fit well with BARCA.
Because we are always pressured to win trophies in each season, and to play well (pleasing for the eye).
Both, to win trophies, you will need players with at least some experience, and to play beautiful, you will again need players who know our system, our mechanisms and who have a chemistry with other starters.
So, in short, unless if your name is Messi, or if you aren't La Masia talent, who is familiar with our style, then young, foreign kids will extremely rarely have an immidiate impact in our club.
And then again, since Barca rarely have years to wait and develop players, majority of players who don't shine in 2-3 years are sold.
This is in shortest, why someone like Coutinho or Griezmann have way higher chances to fit much faster and to make an impact than Dembele.
In the last 20-ish years, after R9, the only youngish guys (outside of La Masia) who had impact soon after coming were Ronaldinho (aged 23), Etoo (aged) 24 and Neymar.
But even Neymar needed some time and even then some of us never said that he is a good fit.
Barcelona, trophies, huge pressure, our unique style of play which requires lots of learning and foreign, young, unexperienced kids=create happy endings extremely rarely.
That is why I am not a huge fan of too young players at Barca.
And then, a foreign kid who wants to make it here, needs to have absolutely everything.
Skills, IQ, bravery, mental strength, ability to fit and evolve his game to our style, injury proneness.
If you lack in any area, your Barca future is in big danger.
So, when you buy a 25-26 years old guy like Coutinho, you know more about all areas of his game and that he has way more experience.
Cou has experience, proven IQ, proven bravery, played in several clubs so he will be able to adapt, we have a larger sample of infos about his injury proneness, mental strength in tough moments.
While with kids like Dembele, we don't know anything.
Majority of areas are unknown or we have a small sample and everything regarding him is a huge gamble.
So, I wouldn't call this just a hate towards young players.
It is way more complicated, with statistically (over history) extremely low success rate for our club.
