I insist, it's not simply because of popularity and amount of resources, which is what you imply.
The resouces dedicated by Spain to soccer is/are certainly not bigger than in UK, where soccer is almost a religion, or in countries that are much bigger and richer.
It's mainly about the training methods and that's not simply explained by the action of government.
The revolutionary system applied by Guardiola in soccer is not a result of that, it's a continuation of the work done by other masters in his field (some of them not even Spanish) which are not related to any action from governemnt.
Similar goes to Abdulmanap Nurmagomedov creating two p4p talents in a row as Khabib/Islam, or how suddenly Australia produces two p4p talents as Volk/Israel from a country that doesnt even dedicate such a huge amount of resources to the matter.
Are Guardiola, Abulmanap or Eugene Bareman a result of the "huge resources" dedicated to their activities from the government of Spain, Daguestan or Australia in comparison with other regions?....Nah, not really. It's way more complex/uncertain than that.
