Day 1 of the men's Olympic soccer tournament came and went, and now, we're already more than halfway through the group stages. 

There have been goals, saves and controversial calls — just ask Argentina — but the "win or go home" time is now for several teams in the tournament, including the U.S. men's soccer team. A lot of games will come down to the wire and teams must decide if they want to play a risky or safe playing style to try and collect all three points. 

Here's a brief breakdown of how each team can, or can't, qualify for the quarterfinals. 

How can the U.S. men's soccer team advance?

The U.S. men's soccer team earned a crucial win against New Zealand to keep its hopes of playing at the Olympics beyond July 30 alive. Not only did the team get a W, but it also erased its minus-3 goal differential from its first game against France. With its goal different now at zero, the U.S. is in much better shape for its upcoming game against Guinea.

Here's how the table is currently shaped for Group A:

  1. France - 6 points
  2. USA - 3 points
  3. New Zealand - 3 points
  4. Guinea - 0 points 

The U.S. is in control of its own destiny, and there are three ways the U.S. can advance to the quarterfinals: 

  • Win against Guinea
  • Tie against Guinea and New Zealand ties or loses to France
  • Lose to Guinea and New Zealand lose to France

Of course, the U.S. would want a win against Guinea to seal the deal, but Guinea itself looked impressive against New Zealand and France despite losing both matches by one goal. It too will have a say on if it deserves to move on. Based on what has been on display from both sides, the U.S. appears to be the better team and is favored to keep going in the tournament. 

As for the rest of the group, here's what the teams must do to advance:

France 

  • Win or tie against New Zealand 
  • Lose to New Zealand and Guinea wins/ties
  • Lose to New Zealand and the U.S. wins but doesn't better France's goal difference

New Zealand 

  • Wins against France and the U.S. loses or ties 
  • Ties against France and the U.S. loses

Guinea

  • Win against the U.S. and New Zealand loses (must better New Zealand's goal difference)
