Athletic's width and Sociedad's midfield connections make the derby a contest over the first useful forward pass. Athletic's recent large scorelines contain more finishing efficiency than sustained chance volume. Vancouver and Seattle also have functioning attacks alongside specific gaps in recovery and box coverage. In both matches, attacking output and control of the final margin need separate treatment.
Sociedad have recently created league chances through Sučić, Guedes and the next runner. Athletic must redistribute Galarreta's first-pass role after his injury against Getafe, while Guruzeta remains unavailable. Canales is available and Sancet has reportedly recovered, but their joint workload is not established by those returns.
Athletic spared most of their core players in the cup, so the case is about the midfield and receiving matchup rather than a tired home team. Sociedad's routes give them a way to answer pressure and keep the contest level through its later phases. That's why I'm siding with Real Sociedad to avoid defeat.
Vancouver's replacement supply worked against San Diego, with Larraz finding White and other lines contributing. Seattle retain Rusnak, Cristian Roldan and Joveljic, giving them a credible route to attack the space beyond Vancouver's advancing players. Vancouver still allowed substantial second-half chances while protecting their lead.
Cubas remains absent from the recovery role and Elloumi is now suspended after playing the previous match. Seattle's Yeimar absence continues, while Morris and Arriola have recent minutes and Rothrock is reportedly available as another option. I expect Seattle to find enough forward connections to stay competitive, which is why I'm siding with the Sounders to keep the result close.
