Brazil and Morocco headline a packed World Cup day, with several dark horses in focus

The article previews a full day of World Cup action, starting with Qatar against Switzerland on Saturday at 22:00 in Group 2 in San Francisco. Switzerland are clear favorites and are expected to beat the tournament hosts' winless-looking side, with hopes of finally getting a knockout-stage victory for the first time since 1938 and avoiding a fourth straight last-16 exit. Captain Granit Xhaka, who was excellent in his first Sunderland season, anchors a strong defense, while striker Breel Embolo is under the microscope after visa problems delayed his arrival to the United States. Qatar, who lost all three games when they hosted the last World Cup, are trying to improve their image under coach Julen Lopetegui, with Akram Afif, and his two straight Asian Cup titles, as their main attacking threat.
