Philadelphia Union arrive at Subaru Park with a compact 4‑3‑3 that presses high and funnels play through Cavan Sullivan’s vertical passing, giving them control in midfield and a steady supply to Milan Iloski’s clinical finishing. Their +10 goal difference and 54 goals scored this season show they can turn possession into chances, while their set‑piece routine—sharp deliveries from the back‑post and timely runs from the full‑backs—adds another layer of threat that Real Salt Lake will have to defend against after a cross‑country trip. Real Salt Lake, meanwhile, rely on a quicker 4‑2‑3‑1 shape that looks to spring Sergi Solans and Morgan Guilavogui on the break, using their 11‑goal and 8‑assist outputs to punish any lapses in Union’s high line. With a –4 goal difference and a defense that has conceded as many goals as it has scored, RSL will need to stay organized, limit the Union’s transition threat, and hope that a well‑timed counter or a dead‑ball situation can swing the match in their favor on the road.
