CONCACAF's own Champions League has plenty of storylines as the first leg games of the quarterfinal round kick off Tuesday night with lone MLS representative Houston Dynamo hosting Mexican First Division team Atlante.
Perhaps the best story of the continental competition so far is the surprise run of the Montreal Impact and Puerto Rico Islanders, two underdog squads from the
American (USL) First Division that happen to hail from outside the borders of the contiguous United States. Defending champ Montreal will host a struggling Santos Laguna of Mexico on Wednesday,
while USL runner up Puerto Rico will face an injury-plagued Marathon of Honduras on Thursday.
In other matchups, the CCL will also feature its first ever derby when Mexico City's UNAM
Pumas, the CCL's only undefeated team, meets Cruz Azul on Wednesday.
