The anticipation for today's World Cup match-up of Team USA against Belgium has reached fever pitch.
American soccer hysteria has proven trans-Atlantic. CNN's Chris Cuomo caught these supporters chanting and cheering Monday night.
Yet the mood will become decidedly more serious come 4 pm ET Tuesday, when the USA-Belgium match kicks off and only the winner will advance.
With star striker Jozy Altidore slated to return, the U.S. team is cautiously optimistic that it can defeat the Belgians.
And Cuomo chatted with Sports Illustrated's Grant Wahl to discuss potential factors that could boost or stymie Team USA's success.
Will the nationality and spoken language of the referee make a difference?
Likely not, Wahl said, noting that the Algerian referee assigned to Tuesday's match may have French in common with the Belgians, but has officiated two "very good games" so far during this World Cup.
"I think Jurgen Klinsmann is playing some mind games here," Wahl said, referring to the U.S. coach's apparent dissatisfaction about the referee assignment.
Will Ramadan, the holy month during which Muslims fast during the day, play a factor?
Negative, Wahl predicted. He said Belgium's Muslim players are not strictly observing Ramadan at this point in the tournament.
Regardless of the match's outcome, one fact is glaringly clear: soccer is more popular than ever.
"These are the biggest television audiences we've ever seen in the United States for soccer," Wahl said.
