This is alarming, because the young population should dominate over the older population , which is why it is also due to fewer players, it is a shame because when we look at the Italian technique it is exquisite and I like their football, in addition now young people have the idea of not having children due to the level of commitment they have, they only want to do activities for themselves, this could become much more complicated in the near future, especially for football.
Even if it is a problem, Italy should still have enough young players who can be developed to play at the national level. After all, Japan faces demographic challenges even worse than Italy, yet their football achievements in recent years have actually surpassed Italy. They have qualified for the round of 16 several times and even beaten major European teams. This is because Japan has a strategic, long-term vision for the development of its football; a well-established system, a young population that is consistently nurtured, and more. That is why Japanese football remains in excellent condition, even though it is not the most popular sport in the country.
The various officials and employees in charge of the Italian football association are responsible for the player crisis in the Italian team. Maybe Italy was not very attentive to their football, which is why now they are not able to find good quality players on whom good expectations can be expected. In this case, you have given a good example of Japan, Japan is not as popular a country in football as Italy, but Japan has been performing quite well in the World Cup tournaments recently, but most of the Japanese players do not get the opportunity to play many matches like that outside the World Cup and Japanese players also do not get the opportunity to play in any big club in Europe. Maybe the situation in the Italian team is very bad now, but if Italy tries from now on, then in the next few years their team will be full of good players again and they will return to good performance again.
