The tableau interactive cards will make their return with the MLS season, but, due to demand, here is a return of the 2010 Match Day Quick Reference Card for tonight's game. As always, the lineups are a best guess. For the Seattle Sounders, the biggest question is David Estrada v Eddie Johnson. The Santos Laguna lineup is more variable and is provided by FMF State of Mind. If Herculez Gomez started no one would be surprised. Santos is deep and in between league matches, but traveled as strong a side as they could. Both teams are nominally similar in their formations, so there will not be obvious spatial mismatches, instead it will be the players that determine victory.
Since many readers are taking some people new to live and local soccer you may want to print this out. You can also use it as a reference during the game on your phone via the SB Nation mobile apps or through a pure web experience.
