Im fed up how some of you guys like to play the role of Nostradamus.
You need to play Nostradamus.
Clubs, directors and coaches need to do that.
They need to decide:
1. which player has the highest potential to turn into a good player for our team based on his skills, potential and based on other players whom we have on that position
2. then they need to decide how many chances he will get, and how often
3. plus, they need to decide whether he is good enough in some moment to become a starter, or he needs more chances.
Or eventually, if he is not good enough and he doesn't deserve more chances
Now, you see, all of these things are somewhat Nostradamus-esque things (except if you are 2 levels better than everyone, like Messi, or two classes weaker than everyone, in those cases everyone will see that you are just good enough or just poor).
In all other cases, those people need to decide and play Nostradamus about whom will they pick, who will get chances, how many chances, how often, and until when this test period will last.
If we weren't playing a Nostradamus, or if the board and coaches wouldn't do the same, then all young players would get the same amount of chances, and we would be wasting time.
Football and young player's development is a one big gamble and one big gambling/predicting/Nostradamus game.
Teams who are best in that game will get the highest number of good predictions, and they will waste the lowest amount of time on wrong judgements/players.
Teams who are bad in the guessing game will lose years and years (and lots of points and trophies) while waiting/having faith/giving too many chances to wrong players.
You just can't give chances to everyone.
And you can't give an unlimited amount of chances to everyone.
