The defending champions have been afforded little time to experiment with tough matches against the Netherlands and Chile before facing Australia in Group B.
The team’s core is aging but still capable, while an incoming crop of young talent will offer Del Bosque further options.
Here are five Spain players to watch:
The Brazilian-born Costa has chosen to play for his adopted homeland of Spain, which has not possessed a player with his qualities since it began its trophy-winning ways at the 2008 European Championship.
Costa’s gritty, physical play lends better to open space and long balls compared to Spain’s short passing, possession style, with the quick-tempered striker terrorizing defenses when given space to run at them.
Iker Casillas has been relegated to backup goalkeeper at Real Madrid, but the Spain captain has been stellar in that role by leading his club to the Copa del Rey final and deep into the knockout stages of the Champions League.
