Philly needs the US Open Cup to push them to the next phase of a long rebuilding process. Kansas City needs it to jumpstart them out of another late season lull. PPL Park was electric in the 2014 final, and it will be again tonight.
Match previews
Preview: Union at New England Revolution
Philly will be peeking ahead to the USOC final, but New England needs points to secure the best playoff spot in a tight race. It all adds up to a one-sided contest, but the Union can use this match to improve their defensive shape against a team that moves well in the final third.
Preview: Union vs Houston Dynamo
In the kind of game they need to learn how to win if they want to turn into a consistent playoff contender, the Union has a real chance to steal points at home against a Houston side struggling with injuries and suspensions.
Preview: Union vs Columbus Crew
Philly needs all three points against a Columbus side that welcomes Kei Kamara back into the fold.
Preview: Union at San Jose Earthquakes
San Jose went undefeated in August despite not playing particularly well. They will be missing a slew of key players Saturday, including important holding midfielder Anibal Godoy.
Preview: Union vs New England Revolution
The Revs have been terrible on the road, but they badly need to take three points on Saturday. Philly will look very different if Jim Curtin selects Vincent Nogueira over Michael Lahoud.
