The Seattle Sounders, the only team with a perfect record in the Leagues Cup, are preparing to face a desperate Club Puebla in the quarterfinals. Despite Puebla's struggles in their domestic league, a recent coaching change and their Leagues Cup success make them a "dangerous" opponent, according to Sounders coach Brian Schmetzer. Seattle is seeking to bounce back from a recent loss that snapped their 10-match unbeaten streak.
