If Christian Pulisic is out vs. Australia, it’s a problem for USMNT. Who can solve it?

USMNT star Christian Pulisic has been training separately from his teammates for a third consecutive day at Great Park in Southern California, nursing an injured left calf and wearing a compression sleeve during limited workouts. The team has described his status as 'day to day' ahead of Friday's World Cup Group D match against Australia in Seattle. Coach Mauricio Pochettino is exploring replacement options as Pulisic's availability remains uncertain for a game that could determine the Group D winner.
