Brazil trusted its defense even more than Neymar to keep its Copa America title. It was a move that failed.

Argentina’s 1-0 victory at the Maracana Stadium on Saturday proved that the Selecao’s defensive prowess was not as strong as its players and coach have shown. Now coach Tite will have to rethink some of his alternatives, as he promised to use Copa America as a testing ground ahead of the World Cup in Qatar.

Argentina’s winner came in the 22nd minute after Rodrigo de Paul made a long pass to Ángel di Maria. The 33-year-old veteran striker counted on poor defending by left-back Renan Lodi to take control and lob it past goalkeeper Ederson.

Brazil had conceded only two goals in the tournament before the final. But Di Maria knew that Lodi could possbly be beaten.

“Before the match I told him (de Paul) that the left-back slept a little in the marking,” the Argentinian striker said after the match. Brazil’s most frequent starter in the position, Alex Sandro, was recovering from injury.
