Pulisic, Reyna, Weah or Aaronson? USMNT World Cup lineup decisions

By and large, Gregg Berhalter knows what the U.S. men's national team will look like at the World Cup.

From choosing a starter in goal to deciding who starts up top, several key positions remain in flux just weeks before the U.S. arrives at the world's biggest tournament.

But those final few spots may be vital and those last few battles to be in the starting XI could be the difference between success and failure at the World Cup.
