Real Salt Lake hosts Herediano, a Costa Rican club, in a pivotal CONCACAF Champions League soccer matchup (8 p.m., Fox Soccer Channel).
One of these two teams will win the group and advance to the next round of the competition. And here's where it gets somewhat complicated because of tie-breakers that involve goal-differential and goals scored in road games.
To make it as simple as possible, RSL needs to either win 1-0 or, if Herediano scores, win by two goals. For example, a 3-1 or 4-2 win for the home team would be great,
But if RSL wins 2-1, 3-2, or 4-3, it loses. And, of course, a loss or a tie is also bad.
Soccer competitions can be weird.
