Real Salt Lake's recent improvement comes from defenders stepping into the attack and finding runners across the box. Austin have also improved their attacking connections, especially through wide service and follow-up shots. The contest should turn on who combines those entries with better protection of the next ball.
De Fougerolles gives Salt Lake an extra carrier from the back, linking with Marczuk and Guilavogui before Solans attacks the delivery. Their opening goal against St. Louis came before the dismissal, and the same unit also created repeatedly against San Jose. That gives the improvement evidence beyond the later goals against ten players.
Austin's Rosales and Gallagher supply width for Uzuni, whose rebound finish at Kansas City showed the value of following the first shot. Ervin Torres is now out after leaving that match injured; Sabovic was his actual replacement. Salt Lake's recent attacking unit has already operated without Luna and Eneli, while Glad's brief return adds a defensive option.
The opening phase should test Salt Lake's ability to advance its right-sided defender and Austin's ability to answer through the wings. Austin's need to press for a result can open more space as the match progresses. Salt Lake's current combinations meet an Austin defence that still allowed repeated close-range attempts after its changes, so I'm siding with Real Salt Lake to win.
