Bilbao's home pressure meets a Sociedad side that can press or break directly after escaping it. In Vancouver, the Whitecaps' possession and pressing meet Seattle's direct release through its central attackers. Both games should turn on the second useful chance after an opening exchange.
Bilbao can return to the box through the Williams brothers and Berenguer's deliveries, while Sociedad have shown a quick reply through Sučić, Guedes and Oyarzabal. Sociedad's league hosts have repeatedly reached its box, and Bilbao can recycle cleared set pieces into another delivery. Guruzeta and Ruiz de Galarreta were already missing from Bilbao's recent setup; Sancet is reported available after missing recent games, while Sociedad's usual wide and central exits remain. A Bilbao goal can draw a Sociedad response, and either side has a route to keep supplying after that. That's why I'm siding with a lively scoring exchange in the derby.
Vancouver's White and Gauld can play through pressure, but Seattle can answer with Joveljić, Morris and Rusnák when the Whitecaps advance. Vancouver's San Diego win also allowed repeated opposing chances. Cubas missed that game after playing at Colorado, and Elloumi played against San Diego before his suspension removed the forward partnership with White; Seattle's existing absences were already present when its current attackers created against Houston. I expect Seattle to find useful exits against the changed Vancouver midfield and keep this match close, so I'm siding with Seattle's protected result.
