As we know, Zardes has been with the US camp for most of January already. They're playing Costa Rica next week and Luis Diaz just got called up for Costa Rica: https://www.mlssoccer.com/post/2020...s-called-costa-rican-national-team-bout-usmnt Africa held their draw for World Cup Qualifying groups this week. The 40 remaining teams are split into 10 groups, and the 10 group winners will play home-and-home series against one of the other winners (in November 2021) to determine the 5 qualifiers. Ghana is in a group with South Africa, Zimbabwe, and Ethiopia. So those'll be some big games between Ghana and South Africa, whenever they're scheduled for. (Might not be until 2021.)
Zardes and Diaz both on the bench today at kickoff for the US/CR game, but David Guzman and Giancarlo Gonzalez are both starting.
