Three Major League Soccer teams and several U.S. Men's National Team players engage in moral combat for the second legs of the CONCACAF Champions League quarterfinals this week.

All of the MLS teams enter the second leg with everything to play for.

Seattle Sounders FC and USMNT forward Eddie Johnson host USMNT midfielder Jose Tores' Tigres de la UANL.  Tigres won the first leg at home 1-0. Without an away goal, the Sounders need to win while not conceding an away goal.  If Tigres score, the away-goals rule put the Sounders in the position of needing to win by at least two goals. Coming home to one of the best home crowds in MLS will boost the Sounders' confidence.

USMNT midfielder Brad Davis scored the lone goal in the Houston Dynamo's 1-0 first-leg win over Santos Laguna and USMNT forward Hercules Gomez. The Dynamo possess the opposite circumstance of the Sounders, any away goal puts the pressure on Santos to win by more than one on their home pasture. MLS teams typically struggle in Liga MX climes, however, so the Dynamo will need something special to keep their first-leg margin.

The LA Galaxy still miss USMNT superstar Landon Donovan, but USMNT halfback Omar Gonzalez was dominant in their away leg at Herediano.  The sides played to a 0-0 draw in Costa Rica and the Galaxy hope to draw a friendly home crowd to pull out a win and advance to the semifinals.
