I think you see this world cup start a tad bit of a revolution in South America. The sport is being dominated by midfielders. South America is known for its attacking talent it contributes, but where they lack is the quality in the midfield. If I am Argentina, Brazil, Uruguay etc. I focus strongly on development of quality midfielders: Going into 2022 world cup its going to be 20 years since a South American winner.... crazy to think about
Just from a pure midfield perspective going forward with talent under the age of 26:
Brazil: Coutinho, Casemiro, Fabinho, Talisca, Fred, Rafinha, Allan, Fernando, Danilo, Wendel
Argentina: Lanzini, Paredes, Pereyra, Escalante, Lo Celso, Kranevitter, Ascacibar
Uruguay: Torreira, Vecino, Bentacur, Valverde, Nandez
Colombia: James Rodriguez, Barrios, Anor, Lerma
Chile is on the way down, its just looking like all the eggs for South America are in the Brazil basket for the time being. I do think if Argentina examines themselves much how Germany did after 2006 they could get it right.
