In a pivotal game at El Sadar, where Osasuna looked to snap a seven-match losing record, the atmosphere from the Copa in San Mamés carried over. Confident in his regulars, Vicente Moreno started the same lineup that won 2-3 at Bilbao on Thursday. Following many minutes of respect for one another, Rayo led the way through Camello. The attacker found himself one-on-one with Sergio Herrera after a well-timed run off a feed from Ratiu, and he chipped the ball over the advancing custodian. By successfully thwarting Osasuna's assaults, Íñigo Pérez's squad established a strong defensive line that proved difficult to breach. Ante Budimir's one-off effort was the hosts' only attempt.

Osasuna put in a lot of kilometres and effort, but they were rewarded with nothing, and the stadium was filled with muttering as the visitors swiftly retaliated.
