The Seattle Sounders head into tonight’s second leg against Club León holding a seemingly strong 3-0 lead. But they only need to look to a night earlier to see how precarious that lead can be, as the New England Revolution blew an identical lead against Pumas before ultimately falling in penalties.
On the line is a spot in the Concacaf Champions League semifinals, where New York City FC awaits. This would mark just the second time the Sounders have ever advanced that far in this tournament, and the first time since 2013.
