It will be an unprecedented moment in professional soccer landscape in the Commonwealth of Pennsylvania on Wednesday, when the Pittsburgh Riverhounds travel to Chester to face Major League Soccer's Philadelphia Union in the Lamar Hunt U.S. Open Cup's Round of 16 (7:30 pm kickoff at Subaru Field).

This match-up provides an excellent opportunity for the two managing editors and site founders, John Krysinsky from Pittsburgh Soccer Now and Matt Ralph from Philadelphia Soccer Now to come together on a special edition of Sounding Off on Soccer Podcast to preview the match between two teams going in different directions in their respective leagues.

John and Matt take a look at the match-up and discuss a number of topics: 

• Finally -- a Philadelphia vs Pittsburgh pro soccer match-up 
• Taking a look at Pennsylvania's soccer landscape and various professional rivalries that have come and gone 
• Throw out records and where teams stand in their respective leagues
• Another facinating tactical match-up between Bob Lilley vs MLS coach who's relatively new to his club
• Thoughts on lineup selections for both squads
• Can the Hounds navigate their way against Philadelphia's high press
