Philadelphia is 1-1-3 so far this season. Last time out on Saturday, the Union played Chicago to a 2-2 draw. This game was a true emotional roller coaster as Philadelphia led 2-1 late, only to see Chicago net an equalizer in the 86th minute. Then it looked like the Union would get nothing out of the contest when Chicago was awarded a penalty kick at the end of stoppage time, but Zac MacMath brilliantly knocked away Mike Magee attempt and the follow, salvaging the point.

Real Salt Lake has been a consistent force for years in Major League Soccer. They are the defending Western Conference champs and they will bring a 2-0-3 record into Saturday’s match. Last time out they played Sporting KC to a scoreless draw.
