Argentina coach Lionel Scaloni knows the World Cup won’t be decided in the opening match of the tournament. Four years ago, Argentina lost its opener to Saudi Arabia but went on to win the title. La Albiceleste open their title defense on Tuesday against Algeria in Kansas City, Missouri. Scaloni sounded optimistic about the health of his squad. Lionel Messi has been dealing with a mild hamstring strain but is expected to play. The only real question is Nicolas Tagliafico, who has been working through a muscle tear in the back of his left leg.
