Valentin Rosier

Key strength: Pace and recovery

Overlapping full-back

As CA Osasuna endure a nightmare five-match losing streak that has torpedoed their European ambitions, one figure remains stubbornly defiant in the eye of Pamplona's storm. Valentin Rosier, the 29-year-old French right-back, has been the definition of reliability amid Los Rojillos' freefall—his 2,083 minutes across 26 appearances meaning he's barely missed a minute all season. While his attacking returns read modestly at 1 goal and 1 assist, Rosier's true value lies in those lung-busting overlapping runs and recovery tackles that embody Osasuna's blue-collar DNA. Valued at €3 million and operating in tandem with defensive anchor Enzo Boyomo, the No. 19 brings a combative edge—reflected in four yellow cards—that signals a player willing to put his body on the line. With his 55-rated defensive grit and tireless work rate down the right flank, Rosier represents the one certainty in a campaign spiraling toward crisis. As Osasuna cling to sixth place and desperately seek to arrest their decline, his durability is the thread they must hold onto.
