Just playing around with the formation, trying to find a way to fit Spain's players best and this system works so well with Alba and Carvajal overlapping. Pique, Azpi, Ramos and Busquets provide more than enough cover defensively making them solid, especially with De Gea behind them. Thiago, Silva and Isco are three of the best creative midfielders in the world supplying Morata who is prolific, scoring for fun.
