The Union boast two draws in its opening matches while FCD has two wins on the season.
Philly will be without four players to its roster.
Out: Andre Blake (left knee menisectomy), C.J. Sapong (concussion), Cristian Maidana (left MCL sprain), Eric Bird (hernia)
A 4-2-3-1 will most likely be the chosen formation for Philadelphia.
GK: Rais Mbolhi; RB: Sheanon Williams; CB: Steven Vitoria, Ethan White; LB: Raymon Gaddis; RDM: Vincent Nogueira; LDM: Maurice Edu; RM: Sebastian Le Toux; CM: Fred da Silva; LM: Andrew Wenger; F: Fernando Aristeguieta
Moises Hernandez vs. Le Toux - Hernandez has established himself early as a strong presence in that left back position. He'll see a challenge in Le Toux tonight. Hernandez's worry will be to keep Le Toux from being dangerous on attack. Yes, Aristeguieta will cause problems behind the backline, but Le Toux's skill could be the difference maker. If Hernandez continues his performance from these past games, FCD should be fine.
Keys to Three Points
Eliminate Aristeguieta. The 23-year-old Venezuelan had a pair of goals in last week's 3-3 draw to Real Salt Lake... and it only took four minutes. The Union's forward leads the team in shots, shots on goal and goals on the seaosn. Clearly he will provide a threat to a FCD defense that played well to earn three points last week.
Play Fabian Castillo. The Union's manager Jim Curtan said this week, "Castillo may be the most dangerous guy in the league right now." This couldn't be more true. Castillo showed in full form last week with his streaking runs and dangerous touches inside the box. Although he'll be marked well, FCD needs to continue to bring that attack down the left side through Hernandez and Castillo.
Push Perez. Blas Perez almost saw a hat trick in last Saturday's 3-1 victory over Sporting Kansas City. The Panamanian fired an early goal in the 17th minute before capping his performance with a goal in the 52nd minute. He now has three goals on the season. Perez is finding net, and Dallas can't let this streak die just yet. Find him open in the box, and let him rip.
