The Olympic men's football tournament continues through the group stage tomorrow as each team comes to its second hurdle.
Some of these matches could shape the field for the quarterfinals while others could effectively eliminate some teams from the competition.
It should be a fine day of football and one well worth watching.
However, it is possible that you won't have the time to watch every single match. After all, there are a lot of other interesting competitions going on at the Olympics. And it's not like this is the pinnacle of football competition anyway.
Hence, in an effort to help, I have cut the matches in half and present to you the four that you should definitely watch tomorrow.
Here are previews for the four matches to watch in tomorrow's Olympic football.
