Marseille's attacking width creates several ways forward and space for an opponent to escape. The Basque derby presents a related contest between Athletic's pressure and Sociedad's central outlets. In both matches, defensive organisation has to be judged against the particular supply arriving at it.
Toulouse have recently kept central distances short and sharply limited opponents' accurate attempts. Dønnum's connection to Rowe and Cásseres releasing Tengstedt give them a route into Marseille's spread shape. Messali's injury is a new change after his last-match start, requiring a right-side adjustment; Oppong is reported back in the squad as an attacking option. Gouiri is available for Marseille, whose varied attack remains part of the comparison.
I expect Marseille to take territory and Toulouse to seek the first useful forward pass after regains. Marseille's recent substantial concessions, including while leading, give those away connections room to matter. That's why I'm siding with Toulouse to avoid defeat.
Athletic's rested Williams brothers and Berenguer's deliveries test Sociedad's recent difficulty handling a cross. Sociedad have answered pressure through Sučić and advancing receivers, with Guedes also finding Turrientes arriving centrally. Galarreta's injury changes Athletic's midfield connection; Canales is cleared and Sancet is available again, with his workload still unconfirmed.
The early press and wide attacks should create alternating contests over second balls and space beyond midfield. These are specific attacking routes at both ends rather than a conclusion drawn from derby history. That's why I'm backing goals in Athletic–Real Sociedad.
