SAO PAULO, July 1 (Reuters) - Argentina and Switzerland were
goalless at halftime after the Swiss managed to keep Lionel
Messi fairly quiet in an evenly-contested World Cup last-16 game
Both sides had chances with Switzerland's Josip Drmic put
clean through before the break, only to chip the ball into the
arms of keeper Sergio Romero, while Argentina striker Ezequiel
Lavezzi earlier had an effort saved by Diego Benaglio.
