The expansion of the World Cup will amplify the problem, and it will only become more and more difficult to select a coach for the national team.

There are many such losers in club challenges in the national team field. Except for the major giants in the national team, Queiroz (Oman), Bielsa (Uruguay), McLaren (Jamaica), Rangnick (Austria), Rudy Garcia (Belgium), Lopetegui (Qatar), Montella (Turkey), etc., are basically losers eliminated by the five major leagues. And Prosinecki, who just resigned from Montenegro in September, like Kluivert, proved that talented players may not necessarily be equally good coaches.

This kind of club "floods" coaches of the national team, which has had a huge impact on the ecological environment of "national team football" coaches. It is almost impossible to see Europe's vibrant high-tech young coaches in the national team. Apart from "retirement coaches" like Queiroz, Advocaat, and Lucescu, there are "old fritters" like Aguirre, Catanic, Pizzi, Batista, and Hasek.

It’s hard for you to even think of the last coach who has resigned from the position of coach of the national team and is still able to gain a foothold in the five major leagues? Postkoglu is one, but he was fired by Nottingham Forest after only 39 days in charge. Shin Tae-yong resigned from Indonesia earlier this year and was just fired from Ulsan HD. It is not that easy to return to the club world from the national team to gain a foothold.
