Three of the last four of the 2016-17 CONCACAF Champions League are known: Pachuca and FC Dallas will contest one semifinal; Tigres UANL is waiting for the winner of this quarterfinal between Vancouver Whitecaps and New York Red Bulls.
Vancouver holds the advantage after the first leg. The 1-1 tie at Red Bull Arena gave the Whitecaps an away goal - and away goals are the tiebreaker if the teams are still level after 90 minutes of the second leg. So RBNY has to score in this game to have any chance of getting to the semifinals.
