The delayed Summer Olympic Games in Tokyo finally get underway this week, with the men's soccer tournament set to start on July 22. Four MLS players made the journey to Japan to compete for their U-23 national teams, representing three countries.

All matches are available across NBC's broadcast channels, as well as NBCOlympics.com. Here's a breakdown of those players and when to watch them as they aim for Olympic success.

Argentina: Ezequiel Barco (Atlanta United), Claudio Bravo (Portland Timbers)

Youth internationals Barco and Bravo are part of a team that won Conmebol''s Olympic qualifying tournament in February 2020, before the COVID-19 pandemic delayed the Olympic Games. Bravo started six of the seven matches during the qualifying tournament, while Barco has one goal in Argentina's pre-tournament warmups, a late penalty against Denmark in June.

Argentina will face Australia, Egypt and Spain in Group C.

Australia: Riley McGree (Charlotte FC)

A member of incoming MLS expansion side Charlotte FC, McGree will compete with an Australia team back at the tournament for the first time since 2008. The midfielder is fresh off making his full international debut after years in the Australia youth setup, recording his first senior cap last month before beginning final preparations for the Olympics.
