Brazil enters its final days of preparations for the World Cup paying extra attention to its defense.

Coach Luiz Felipe Scolari spent part of the team's training session on Monday making adjustments to the defensive setup, stopping practice several times to reposition players until he was satisfied.

Although Brazil didn't concede a goal in its two warm-up matches before the World Cup, Scolari said he was not completely satisfied with how his squad played defensively. He didn't even like how the team practiced at times, and publicly said his players were giving up too much space for counterattacks.

Right back Daniel Alves acknowledged that Brazil's defense isn't perfect, and said they are working to improve it before the opener against Croatia on Thursday.
