Also top clubs bring the world's best players together - Emirates Marketing Project, Real Madrid, Barcelona, Bayern etc. In WC football they get dispersed all over the place and each manager has to make do with the best of whatever his country happens to have, eg Ronaldo/Portugal, Eriksen/Denmark, Salah/Egypt. And some of the world's best don't even make it to the tournament, eg Bale/Wales, Robben, Van Dijk/Holland, Chiellini/Italy, Aubameyang/Gabon, Dzeko/Bosnia.
I think that's where Germany and Spain have benefitted over the years, and to a certain extent Italy. Most of the German team from the last 4 years or so play for Bayern Munich. Most of the Spanish sides have played for Real and Barca. Most of the Italians have played together for Juve.
